Cold Chemistry Molecular Scattering and Reactivity Near Absolute Zero

Cold Chemistry Molecular Scattering and Reactivity Near Absolute Zero

Author: Olivier (Universite Paris-Sud, France) Dulieu Format: Hardback Release Date: 14/12/2017

Recent years have seen tremendous progress in research on cold and controlled molecular collisions, both in theory and in experiment. The advent of techniques to prepare cold and ultracold molecules and ions, to store them in optical lattices or in charged quasicristalline structures, and to use them in crossed or merged beam experiments have opened many new possibilities to study the most fundamental aspects of molecular interactions. At the same time, theoretical work has made progress in tackling these problems and accurately describing quantum effects in complex systems, and in proposing viable options to control chemical reactions at ultralow energies. Through tutorials on both the theoretical and experimental aspects of research in cold and ultracold molecular collisions, this book provides advanced undergraduate students, graduate students and researchers with the foundations needed to understand this exciting field.

Acoustic Cavitation and Bubble Dynamics

Acoustic Cavitation and Bubble Dynamics

Author: Kyuichi Yasui Format: Paperback / softback Release Date: 03/11/2017

This brief explains in detail fundamental concepts in acoustic cavitation and bubble dynamics, and describes derivations of the fundamental equations of bubble dynamics in order to support those readers just beginning research in this field. Further, it provides an in-depth understanding of the physical basis of the phenomena. With regard to sonochemistry, the brief presents the results of numerical simulations of chemical reactions inside a bubble under ultrasound, especially for a single-bubble system and including unsolved problems. Written so as to be accessible both with and without prior knowledge of fundamental fluid dynamics, the brief offers a valuable resource for students and researchers alike, especially those who are unfamiliar with this field. A grasp of fundamental undergraduate mathematics such as partial derivative and fundamental integration is advantageous; however, even without any background in mathematics, readers can skip the equations and still understand the fundamental physics of the phenomena using the book's wealth of illustrations and figures. As such, it is also suitable as an introduction to the field.

Ab Initio Calculations Methods and Applications

Ab Initio Calculations Methods and Applications

Author: Maria Emilova Velinova Format: Hardback Release Date: 01/11/2017

The book entitled Ab initio Calculations: Methods and Applications provides an overview of the most used ab initio quantum methods and their applications in different fields. Ab initio calculations offer results and details that are not obtainable from experimental data and a degree of assurance which is not accessible with the empirical methods. The methods Hartree-Fock, Moller-Plesset Perturbation theory and Coupled Cluster theory are discussed. Both their accuracy and computational performance are summarized in the first part of the book. The rest of the book is emphasizing on the significant advances in the implementation of the ab initio methods in the last years. Biological applications of the ab initio methods, subject to part 2 of the book, are mainly focused on the modelling of enzymatic catalysis and active-site chemistry. Here are also shown interesting investigations of other phenomena, such as tautomerism, occurring in nucleic acid bases and important for the stability of DNA, considering that tautomerism partially explains the structure of nucleic acids and their mutations. Another interesting phenomenon as molecular photostability happening in nitrogen containing heterocycles, DNA bases and base pairs is briefly described. In the last years, materials-science applications are fast developed and currently involve examination of highly complex structures. Both bulk and surface properties can be calculated for solids as the results are in excellent agreement with experimental data. Here a special attention is given to the investigation of materials with optical properties and of nanocrystals for potential use as electronic devices. The interest to the application of the ab initio methods to nanotechnology is quite recent and corresponds to the increasing applicability of these materials in various types of devices. The systems that have been considered in this book are carbon nanostructures as graphene, buckyballs and nanotubes. In particular, the special effect of the quantum-restricted size and structural modification on both chemical and electrical properties are investigated. The continuous theoretical developments and the decrease in the cost/performance of computing guarantee the fast progress of the ab initio calculations in the next years, advancing toward the goal of achieving a complete agreement with the experiments.

Multi-shell Polyhedral Clusters

Multi-shell Polyhedral Clusters

Author: Mircea Vasile Diudea Format: Hardback Release Date: 30/10/2017

This volume presents new methodologies and rationalizes existing methods that are used in the design of multi-shell polyhedral clusters. The author describes how the methods used are extended from 2D-operations on maps to 3D (and higher dimensional) Euclidean space. A variety of structures is designed and described in detail and classified giving rise to an atlas of multi-shell nanostructures. The book therefore sheds a new light on the field of crystal and quasicrystal structures, an important part of nanoscience and nanotechnology. The author goes on to show how the recently established methods are used for building complex multi-shell nanostructures and how this completes the existing information in the field. The atlas of such structures is completed with atomic coordinates (included as supplementary material). The content of this book gives a useful insight into structure elucidation and suggests new material synthesis.

Quantum Chemistry A Concise Introduction

Quantum Chemistry A Concise Introduction

Author: Ajit Thakkar Format: Paperback / softback Release Date: 28/09/2017

This book provides non-specialists with a basic understanding ofthe underlying concepts of quantum chemistry. It is both a text for second or third-year undergraduates and a reference for researchers who need a quick introduction or refresher. All chemists and many biochemists, materials scientists, engineers, and physicists routinely user spectroscopic measurements and electronic structure computations in their work. The emphasis of Quantum Chemistry on explaining ideas rather than enumerating facts or presenting procedural details makes this an excellent foundation text/reference. The keystone is laid in the first two chapters which deal with molecular symmetry and the postulates of quantum mechanics, respectively. Symmetry is woven through the narrative of the next three chapters dealing with simple models of translational, rotational, and vibrational motion that underlie molecular spectroscopy and statistical thermodynamics. The next two chapters deal with the electronic structure of the hydrogen atom and hydrogen molecule ion, respectively. Having been armed with a basic knowledge of these prototypical systems, the reader is ready to learn, in the next chapter, the fundamental ideas used to deal with the complexities of many-electron atoms and molecules. These somewhat abstract ideas are illustrated with the venerable Huckel model of planar hydrocarbons in the penultimate chapter. The book concludes with an explanation of the bare minimum of technical choices that must be made to do meaningful electronic structure computations using quantum chemistry software packages.

Structural Chemistry Principles, Methods, and Case Studies

This book explains key concepts in theoretical chemistry and explores practical applications in structural chemistry. For experimentalists, it highlights concepts that explain the underlying mechanisms of observed phenomena, and at the same time provides theoreticians with explanations of the principles and techniques that are important in property design. Themes covered include conceptual and applied wave functions and density functional theory (DFT) methods, electronegativity and hard and soft (Lewis) acid and base (HSAB) concepts, hybridization and aromaticity, molecular magnetism, spin transition and thermochromism. Offering insights into designing new properties in advanced functional materials, it is a valuable resource for undergraduates of physical chemistry, cluster chemistry and structure/reactivity courses as well as graduates and researchers in the fields of physical chemistry, chemical modeling and functional materials.

Applications of Quantum Dynamics in Chemistry

Applications of Quantum Dynamics in Chemistry

Author: Fabien Gatti, Benjamin Lasorne, Hans-Dieter Meyer, Andre Nauts Format: Hardback Release Date: 14/07/2017

This book explains the usage and application of Molecular Quantum Dynamics, the methodology where both the electrons and the nuclei in a molecule are treated with quantum mechanical calculations. This volume of Lecture Notes in Chemistry addresses graduate students and postdocs in the field of theoretical chemistry, as well as postgraduate students, researchers and teachers from neighboring fields, such as quantum physics, biochemistry, biophysics, or anyone else who is interested in this rising method in theoretical chemistry, and who wants to gain experience in the opportunities it can offer. It can also be useful for teachers interested in illustrative examples of time-dependent quantum mechanics as animations of realistic wave packets have been designed to assist in visualization. Assuming a basic knowledge about quantum mechanics, the authors link their explanations to recent experimental investigations where Molecular Quantum Dynamics proved successful and necessary for the understanding of the experimental results. Examples including reactive scattering, photochemistry, tunneling, femto- and attosecond chemistry and spectroscopy, cold chemistry or crossed-beam experiments illustrate the power of the method. The book restricts complicated formalism to the necessary and in a self-contained and clearly explained way, offering the reader an introduction to, and instructions for, practical exercises. Continuative explanation and math are optionally supplemented for the interested reader. The reader learns how to apply example simulations with the MCTDH program package (Multi Configuration Time Dependent Hartree calculations). Readers can thus obtain the tools to run their own simulations and apply them to their problems. Selected scripts and program code from the examples are made available as supplementary material. This book bridges the gap between the existing textbooks on fundamental theoretical chemistry and research monographs focusing on sophisticated applications. It is a must-read for everyone who wants to gain a sound understanding of Molecular Quantum Dynamics simulations and to obtain basic experience in running their own simulations.

Mechanistic Studies on Transition Metal-Catalyzed C-H Activation Reactions Using Combined Mass Spectrometry and Theoretical Methods

Mechanistic Studies on Transition Metal-Catalyzed C-H Activation Reactions Using Combined Mass Spectrometry and Theoretical Methods

Author: Gui-Juan Cheng Format: Hardback Release Date: 26/06/2017

This thesis presents detailed mechanistic studies on a series of important C-H activation reactions using combined computational methods and mass spectrometry experiments. It also provides guidance on the design and improvement of catalysts and ligands. The reactions investigated include: (i) a nitrile-containing template-assisted meta-selective C-H activation, (ii) Pd/mono-N-protected amino acid (MPAA) catalyzed meta-selective C-H activation, (iii) Pd/MPAA catalyzed asymmetric C-H activation reactions, and (iv) Cu-catalyzed sp3 C-H cross-dehydrogenative-coupling reaction. The book reports on a novel dimeric Pd-M (M = Pd or Ag) model for reaction (i), which successfully explains the meta-selectivity observed experimentally. For reaction (ii), with a combined DFT/MS method, the author successfully reveals the roles of MPAA ligands and a new C-H activation mechanism, which accounts for the improved reactivity and high meta-selectivity and opens new avenues for ligand design. She subsequently applies ion-mobility mass spectrometry to capture and separate the [Pd(MPAA)(substrate)] complex at different stages for the first time, providing support for the internal-base model for reaction (iii). Employing DFT studies, she then establishes a chirality relay model that can be widely applied to MPAA-assisted asymmetric C-H activation reactions. Lastly, for reaction (iv) the author conducts detailed computational studies on several plausible pathways for Cu/O2 and Cu/TBHP systems and finds a reliable method for calculating the single electron transfer (SET) process on the basis of benchmark studies.
