The role of the computer in the practice of organic chemistry has been firmly established over the past decade. Its uses as a large scale information storage and retrieval device in chemistry have been too numerous to mention. More recently, the applicability of computers to the problem of discovering valid and reasonable synthesis routes for organic molecules has been demonstrated. This has been both as an adjunct to the 1 chemist in the on-line interactive mode ,2,3 and also as a wholly computer-directed system seeking to simulate the intelligent prob- 4 lem-solving activity of the human organic synthetic chemist. ,5 In all of these computer applications to organic chemistry, it has been necessary to devise some computer-compatible repres- tation of an organic molecule that is both canonical and c- venient for table look-ups. This is in order that entities that have been constructed at different times under different circumstances can be identified and classified, with identical molecules being recognized as such even if their connection matrices list the elements of the molecule in different orders.

It has been said that modern molecular theory is founded on essentially graph-like models located in some appropriate embedding space. The idea may be extended to physical theory, and it is this that provides the raison d'etre for this collection of papers. Today there is almost no branch of chemistry, including its more recent relatives in polymer science and biology, that is not enriched by (or enriching) the mathematical theory of graphs. The impact of graph-theoretical thinking in physics has, with some notable exceptions, developed more slowly. In 1847, G.R. Kirchoff founded the theory of electrical networks as a graph-theoretical structure, and as a result also made significant contributions to the mathematics of graph theory. This tradition has continued into the newer sciences such as telecommunications, computer science and information science.

This volume is devoted entirely to inorganic and organometallic stereochemical subjects. Discusses the systematic notations that have been developed to satisfy the needs for a rational and systematic stereochemical nomenclature. Reviews the stereochemical aspects of the changes of bonding at carbon centers induced by metals, either catalytically or stoiciometrically. Also reviews the major achievements in current stereochemical research--the synthesis of asymmetric compounds mediated by transition metals. Discusses the structures of transition metal carbonyl clusters, summarizing recent progress in this expanding area and providing a semiquantitative rationalization of the structures for these clusters.
