Now chemical DFT is a diverse and rapidly growing field, its progress fueled by numerous developing practical descriptors that make DFT as useful as it is vast. With 34 chapters written by 65 eminent scientists from 13 diffe

Includes applications in the frontiers of reactivity principles, and introduces dynamic and statistical viewpoints to chemical reactivity and challenging traditional concepts such as aromaticity. * Written by specialists in the field of chemical reactivity* An authoritative overview of the research and progress * An essential reference material for students




Chemistry & Chemical Reactivity


Book Description

"Chapter Goals" and "Chapter Goals Revisited" are two new features in this revision. Each chapter starts with a list of goals that allows students to see what is ahead. The chapter concludes with a repetition of that list with summary information added. General ChemistryNow is correlated to this list. New to this edition are dozens of "Active Figures" to help students visualize chemistry in action. These animated versions of text art help students master key concepts from the book. "Active Figures" can be used as demonstrations in the classroom and each figure is paired with a guided exploration and exercise to ensure students understand the concept being illustrated. In-text worked "Examples" follow a four-part structure: "Problem" statement, "Strategy" for approaching the problem, fully worked "Solution," and, where appropriate, a "Comment" on the problem and solution. Through this approach, students learn how to approach a problem rather than merely learning to memorize problem types and memorized solution approaches. Exercises appear throughout the text so students can check their comprehension of the material. Answers are in an appendix. "Problem-Solving Tips" provide readers tips for determining how to approach and solve problems. "Chemical Perspectives" are essays that bring relevance and perspective to a study of chemistry. In order to put chemistry in its historical context, "Historical Perspective" essays describe the people who were key to developing the concepts of the chapter. "A Closer Look" essays describe ideas that form the background to material under discussion or provide another dimension of the subject. - Publisher.




Solvent Effects and Chemical Reactivity


Book Description

This book presents an up-to-date view of theories, practical methods and applications of solvent effects and chemical reactivity in condensed phases. Subjects treated include continuum solvation models, the theoretical basis for the treatment of solvent effects in density functional theory, Monte Carlo simulations of chemical reactions in solution, DFT molecular dynamics simulations, crossing the transition state in solution, valence bond multi-state approach to chemical reactions in solution, quantum theory of solvent effects and chemical reactions. The approaches taken as well as the resulting findings are discussed in detail, thus covering a large part of the methodology currently used in this field. Audience: This volume will be useful to graduate students in chemistry, physical chemistry and biochemistry, to research workers with a background in quantum chemistry and quantum mechanics, to pure and applied quantum chemists, and to industrial molecular modellers.




Graph Theoretical Approaches to Chemical Reactivity


Book Description

The progress in computer technology during the last 10-15 years has enabled the performance of ever more precise quantum mechanical calculations related to structure and interactions of chemical compounds. However, the qualitative models relating electronic structure to molecular geometry have not progressed at the same pace. There is a continuing need in chemistry for simple concepts and qualitatively clear pictures that are also quantitatively comparable to ab initio quantum chemical calculations. Topological methods and, more specifically, graph theory as a fixed-point topology, provide in principle a chance to fill this gap. With its more than 100 years of applications to chemistry, graph theory has proven to be of vital importance as the most natural language of chemistry. The explosive development of chemical graph theory during the last 20 years has increasingly overlapped with quantum chemistry. Besides contributing to the solution of various problems in theoretical chemistry, this development indicates that topology is an underlying principle that explains the success of quantum mechanics and goes beyond it, thus promising to bear more fruit in the future.




Molecular Reaction Dynamics


Book Description

Molecular reaction dynamics is the study of chemical and physical transformations of matter at the molecular level. The understanding of how chemical reactions occur and how to control them is fundamental to chemists and interdisciplinary areas such as materials and nanoscience, rational drug design, environmental and astrochemistry. This book provides a thorough foundation to this area. The first half is introductory, detailing experimental techniques for initiating and probing reaction dynamics and the essential insights that have been gained. The second part explores key areas including photoselective chemistry, stereochemistry, chemical reactions in real time and chemical reaction dynamics in solutions and interfaces. Typical of the new challenges are molecular machines, enzyme action and molecular control. With problem sets included, this book is suitable for advanced undergraduate and graduate students, as well as being supplementary to chemical kinetics, physical chemistry, biophysics and materials science courses, and as a primer for practising scientists.




Chemistry


Book Description

Taking an evidence-first big picture approach, Chemistry: Human Activity, Chemical Reactivity encourages students to think like a chemist, develop critical understanding of what chemistry is, why it is important and how chemists arrive at their discoveries. Flipping the traditional model of presenting facts and building to applications, this text begins with contexts that are real-life and matter to students – from doping in sports, to the chemistry behind the treads of wall-climbing robots. Informed by the latest chemical education research, Chemistry: Human Activity, Chemical Reactivity presents chemistry as the exciting, developing human activity that it is, rather than a body of facts, theories, and skills handed down from the past. Along with the innovative MindTap Reader and OWLv2 learning platform, this text uses unique case studies and critically acclaimed interactive e-resources to help students learn chemistry and how it is helping to address global challenges of the 21st century.
