Symmetry and Combinatorial Enumeration in Chemistry

[Home Position in Top of Index]

  • Bibliographic Data

  • Summary

    • 368 pages containing 21 chapters and appendices. In contrast to traditional textbooks on chemical symmetries based on linear representations and irreducible representations, this book has discussed molecular symmetries in terms of permutation representations and coset representations. This approach (the unit-subduced-cycle-index approach) provides us with versatile tools by which molecular symmetries and combinatorial enumeration of isomers can be discussed on a common basis. In particular, four distinct but relevant methods of combinatorial enumerations developed by the author have been discribed in detail.

    • Coset representations are related to the stereochemical nature of organic and inorganic molecules, where a new concept "chirality fittingness" (or sphericity) has been proposed. Another new concept "subduction of coset representations" is proposed so as to develop four methods of combinatorial enumerations (USCI methods), which have been applied to various combinatorial enumerations.

    A book review by C. Alden Mead has appeared in Journal of the American Chemical Society (1992, 114, 4018--4019). A part of the review is cited below:

    "This book is not so easy going, but the reader who makes the necessary effort will be rewarded by the acuisition of some powerful tools and deep insights. If the coming generation of chemists becomes as familiar with mark tables and their uses as the present generation is with character tables, much of the credit will go to Fujita and the present book."

    Computer-Oriented Representation of Organic Reactions

    [Home Position in Top of Index]

  • Bibliographic Data

  • Summary

    • 371 pages containing 16 chapters and an index. Organic materials of various functions are important factors to enrich our modern life. It is crucial for us to enhance their usefulness on one hand and to minimize their undesirable effects on the other hand. Thus we should control synthetic processes of useful materials, their behaviors under natural and artificial conditions, and decomposition processes of used materials. These tasks require our knowledge on changes of such organic materials, where accumulated items on the changes are systematized so as to realize a well-constructed database of organic reactions. This book deals with a computer-oriented representation of organic reactions in the light of the concept of imaginary transition structure (ITS) proposed by the author. The concept provides us with a versatile methodology to describe, classify, and enumerate organic reactions; and enables us to construct and retrieve an organic-reaction database efficiently.

    Organic Chemistry of Photography

    [Home Position in Top of Index]

  • Bibliographic Data

  • Summary

    • 587 pages containing 21 chapters and an index. In conventional color photography, spectral sensitizers cooperate with silver halide as acceptors of light during the exposure process, color developers reduce silver halide grains during the developing process, and finally the resulting oxidized developers react with couplers to form imaging dyes. Instant color photography gives us an alternative way of realizing excellent color reproduction, in which dyes changing their diffusibility play an important role. The aim of this book is to provide researchers and graduate students with a perspective on how such organic compounds work in color photography and how seemingly miraculous techniques based on organic chemistry lead to color images of high quality. The readers will acquire the philosophy and learn from hints on how to develop functionalized organic compounds.
