Every chemist is aware of the fact that this case is not unique in chemical nomenclature it is the result of continuous and parallel developments in chemistry Accordingly, rules of systematic nomenclature — compounds, reactions, mechanisms - will also develop continuously. 

This situation must be corrected. Society needs a clean and safe enviromnent. It also needs to capitalize fully on new developments in chemistry, biotechnology, and materials science, if the United States is to retain technological leadership and international competitiveness in major segments of indnstry. 

With Helferich s death, we have lost a great scientist and teacher who had a substantial influence on developments in chemistry. His memory will remain fresh with all those who had the good fortune to be his students and colleagues.

For almost 60 years, The Royal Society of Chemistry and its predecessor, The Chemical Society, have published Reports in which acknowledged experts have charted developments in chemistry. 

This book has been written in an attempt to provide students with the mathematical basis of chemistry and physics. Many of the subjects chosen are those that I wish that I had known when I was a student It was just at that time that the no-mans-land between these two domains - chemistry and physics - was established by the Harvard School , certainly attributable to E. Bright Wilson, Jr., J. H. van Vleck and the others of that epoch. I was most honored to have been a product, at least indirectly, of that group as a graduate student of J. C. Decius. Later, in my post-doc years. I profited from the Harvard-MIT seminars. During this experience I listened to, and tried to understand, the presentations by those most prestigious persons, who played a very important role in my development in chemistry and physics. The essential books at that time were most certainly the many publications by John C. Slater and the Bible on mathematical methods, by Margeneau and Murphy. They were my inspirations.

New developments in chemistry can arise from the planning and testing of new synthetic methods. In contemporary chemistry, we can see developments whose roots can be found in biological processes, as the terms signal recognition , replication , autocatalysis or self-replication indicate. Modern ideas in these areas can be found in laboratories where work on peptide chemistry is being carried out.

The concept of atropisomerism developed to a considerable extent following other developments in chemistry, especially those in spectroscopy. Early work by Kohlrausch (4) and Mizushima (3), based on Raman spectra and dipole moment studies, established that rotational isomers—rotamers—must exist in 1,2-dichloroethane. Pitzer established that there are three energy minima when ethane is rotated about its C—C axis (6). Rotamers about single bonds have been found in a wide variety of organic compounds since then, mainly as a result of the application of vibrational spectroscopy to organic molecules (7).

Molecular complexation is a precondition for receptor functions such as substrate selection, substrate transportation, isomeric differentiation, and stereoselective catalysis. Although the investigation of such functions with synthetically derived compounds is a relatively new development in chemistry, they are well known and extensively studied functions in the biological domain. Evolution, gene expression, cell division, DNA replication, protein synthesis, immunological response, hormonal control, ion transportation, and enzymic catalysis are only some of the many examples where molecular complexation is a prerequisite for observing a biological process.

Historically, The Royal Society of Chemistry and its predecessor. The Chemical Society, have published reports of developments in chemistry since the end of the 19th century. By 1967, however, the sheer volume of chemistry published had become so great that it was decided to split the research into specialist areas, and the series Specialist Periodical Reports was born.
