Abstract:

”This text explores methodologies that can be usefully applied to various realistic problems in molecular spectroscopy and chemical dynamics. It covers the direct evaluation of reaction rate constants for both electronically adiabatic chemical reactions on a single adiabatic potential energy surface and non-adiabatic chemical reactions in which two or more adiabatic potential energy surfaces are involved. It also discusses the non-adiabatic tunneling phenomenon that represents one class of non-adiabatic transitions on which the authors have made an extensive research so far”

PREFACE:

On this e book we primarily focus on the next three tunneling phenomena primarily based on our latest theoretical developments: (1) vitality splitting, or tunneling splitting, in symmetric double effectively potential, (2) decay of metastable state by means of tunneling, and (3) tunneling results in chemical reactions. The corresponding bodily processes might be naively understood in phrases of a response path in which (1) two endpoints are fastened, (2) one endpoint is fastened and one is free, and (3) each ends are free. Quantum mechanical tunneling manifests itself in a really wide selection of pure phenomena and the topics we take care of right here represent solely a small portion of the entire space.

Despite the lengthy historical past of research of quantum mechanical tunneling phenomena, nonetheless, the speculation of multidimensional tunneling has not but been satisfactorily developed. Not too long ago, we’ve efficiently developed sensible and helpful strategies relevant to actual multidimensional programs for the above-mentioned issues. Primary theories, sensible methodologies, and precise numerical functions to actual molecular programs are offered in order that the reader can hopefully comprehend the fundamental ideas and dynamics of multidimensional tunneling phenomena and use the strategies instantly in numerous issues of molecular spectroscopy and chemical dynamics, if needed.

Insufficiency of the low-dimensional remedies which might be typically employed for sensible issues and intriguing results of multidimensionality are demonstrated and clarified conceptually in addition to numerically. Moreover, consideration known as to the nonadiabatic tunneling phenomenon, which is sort of ubiquitous in molecular programs and but manifests distinctive and intriguing phenomenon in comparability with peculiar tunneling. On this e book, fairly a little bit of arithmetic is used for the event and clarification of fundamental theories; thus a background data of arithmetic is required on the degree of graduate college students.

This e book is meant as a normal reference for comprehending the phenomena and fixing sensible issues in the fields of chemical physics. H. N. primarily wrote the entire contents and thus is liable for all chapters. G. M. shares duty for Chapters 6, 7, and 8 and Part 9.1. We want to thank all of the collaborators for his or her contributions in the event of the strategies and numerous functions to actual molecular programs that clearly show the usefulness of our strategies. H. N. want to specific his honest due to Nationwide Chiao Tung College in Hsinchu, Taiwan, and other people on the Institute of Molecular Science, Division of Utilized Chemistry, School of Science of the college for offering this good alternative to work on this e book.
