This book was released on 2012-12-06 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last hundred years benzenoid hydrocarbons have constantly attracted the attention of both experimental and theoretical chemists. In spite of the fact that some of the basic concepts of the theory of benzenoid hydrocarbons have their origins in the 19th and early 20th century, research in this area is still in vigorous expansion. The present book provides an outline of the most important current theoretical approaches to benzenoids. Emphasis is laid on the recent developments of these theories, which can certainly be characterized as a significant advance. Em phasis is also laid on practical applications rather than on "pure" theory. The book assumes only some elementary knowledge of organic and physical chemistry and requires no special mathematical training. Therefore we hope that undergraduate students of chemistry will be able to follow the text without any difficulty. Since organic and physical chemists are nowadays not properly acquaint ed lVith the modern theory of benzenoid molecules, we hope that they will find this book both useful and informative. Our book is also aimed at theoretical chemists, especially those concerned with the "topological" features of organic molecules. The authors are indebted to Dr. WERNER SCHMIDT (Ahrensburg, FRG) for valuable discussions. One of the authors (1. G.) thanks the Royal Norwegian Council for Scientific and Industrial Research for financial support during 1988, which enabled him to stay at the University of Trondheim and write the present book.

Available in PDF, EPUB and Kindle. Book excerpt: The present monograph is a continuation of Cyvin SJ, Brunvoll J and Cyvin (1991c), a reference to be found in Bibliography. Naturally, the previous volume is cited frequently here. For the sake of brevity, it is referred to as "Volume I". References to different chapters, sections or paragraphs are given like Vol. 1-1, 1-1.2 or 1-1.2.2, respectively. Also tables and equations in "Volume I" are cited; the very last equation therein, for instance, is Vol. I-{9.9). The present text spans from references to organic syntheses or attempted organic syntheses - - to stringent mathematical theorems proved by graph-theoretical methods. Enumerations of coronoid systems is a substantial part of the work. Algebraic methods involving combinatorics and generating functions are employed on one hand, and computer programming on the other. The whole book is supposed to demonstrate a piece of mathematical chemistry, which can be characterized as lying on the "interfaces between mathematics, chemistry and computer science", a formulation used for the MATH/CHEM/COMP Conferences; d. Cyvin SJ, Brunvoll and Cyvin (1989d) in Bibliography. Financial support to BNC from the Norwegian Council for Science and the Humanities is gratefully acknowledged.

Available in PDF, EPUB and Kindle. Book excerpt: Advances in Theoretically Interesting Molecules: A Research Annual, Volume 2 provides information pertinent to the dynamics of cyclooctatetraene ring inversion. This book deals with bridgehead olefins, which helps to shed light on structure-activity relationships for this most basic functional group. Organized into four chapters, this volume begins with an overview of the involvement of planar, delocalized transition states to account for bond shifting in cyclooctatetraenes, which faces explicit problems in rationalizing the universally low energy demands. This text then examines the carbon-carbon double bond, which is the most ubiquitous functional group in organic chemistry. Other chapters consider the condensed polycyclic benzenoid aromatic hydrocarbons (PAHs), which is a subset of the multifarious class of polynuclear aromatics. This book discusses as well the problem of categorizing the molecular structures of PAHs. The final chapter deals with the reactions and synthesis of Dewar furan. This book is a valuable resource for organic chemists.

Available in PDF, EPUB and Kindle. Book excerpt: The mathematical treatment of coronoid hydrocarbons is a continuation of the authors' previous book Kekulé Structures in Benzenoid Hydrocarbons (Lecture Notes in Chemistry, Vol. 46). The book addresses theoretical and mathematical chemists and graduate students. The treatment includes topological properties of coronoid systems, their enumeration and classification, the number of Kekulé structures and of aromatic sextets.

This book was released on 2013-04-17 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text is an attempt to outline the basic facts concerning Kekul€ structures in benzenoid hydrocarbons: their history, applica tions and especially enumeration. We further pOint out the numerous and often quite remarkable connections between this topic and various parts of combinatorics and discrete mathematics. Our book is primarily aimed toward organic and theoretical chemists interested in the enume ration of Kekule structures of conjugated hydrocarbons as well as to scientists working in the field of mathematical and computational chemistry. The book may be of some relevance also to mathematicians wishing to learn about contemporary applications of combinatorics, graph theory and other branches of discrete mathematics. In 1985, when we decided to prepare these notes for publication, we expected to be able to give a complete account of all known combi natorial formulas for the number of Kekule structures of benzenoid hydrocarbons. This turned out to be a much more difficult task than we initially realized: only in 1986 some 60 new publications appeared dealing with the enumeration of Kekule structures in benzenoids and closely related topics. In any event, we believe that we have collec ted and systematized the essential part of the presently existing results. In addition to this we were delighted to see that the topics to·which we have been devoted in the last few years nowadays form a rapidly expanding branch of mathematical chemistry which attracts the attention of a large number of researchers (both chemists and mathematicians).

Available in PDF, EPUB and Kindle. Book excerpt: The present studies of coronoid systems is a natural continua tion of the corresponding studies of benzenoid systems. Both topics are rooted in organic chemistry through certain polycyclic conjugated hydrocarbons, which are the chemical counterparts of the systems in question. HO'v'Tever, the scope of the present work and corresponding works on benzenoids goes far beyond a chemical motivation. These works are classified under mathematical chemistry, a relatively new designa tion. The book is supposed to have an interest for organic chemists within certain specialities, but still more for theoretical and mathe matical chemists. The last category has been characterized as enfants terribles in the foreword of the first issue of the Journal of Mathe matical Chemistry (1987). Finally, this book may have a considerable interest for mathematicians within combinatorics and gra~h theory. It is supposed that the book will be most useful for researchers, including graduate students, in the pertinent fields. The text contains no advanced mathematics whatsoever and should as such not represent any barrier even for undergraduate students. Here we wish to make some comments on the terminology, which is not standardized and is partly controversial in this field of topolo gical studies of polyhex (benzenoid and coronoid) systems.
