This book was released on 2012-12-06 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is a great challenge in chemistry to clarify every detail of reaction processes. In older days chemists mixed starting materials in a flask and took the resul tants out of it after a while, leaving all the intermediate steps uncleared as a sort of black box. One had to be content with only changing temperature and pressure to accelerate or decelerate chemical reactions, and there was almost no hope of initiating new reactions. However, a number of new techniques and new methods have been introduced and have provided us with a clue to the examination of the black box of chemical reaction. Flash photolysis, which was invented in the 1950s, is such an example; this method has been combined with high-resolution electronic spectroscopy with photographic recording of the spectra to provide a large amount of precise and detailed data on transient molecules which occur as intermediates during the course of chemical reac tions. In 1960 a fundamentally new light source was devised, i. e. , the laser. When the present author and coworkers started high-resolution spectroscopic stud ies of transient molecules at a new research institute, the Institute for Molecu lar Science in Okazaki in 1975, the time was right to exploit this new light source and its microwave precursor in order to shed light on the black box.

This book was released on 2012-12-06 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is amazing how much information can be gleaned from a magnetic resonance spectrum by one who knows. That series of lines on chart paper may conceal anything from energies of activation and spin densities, to conformations and differentiation of isomers. In order to be able to deduce such things about the structure and properties of molecules in a sample, it is necessary to be familiar with the underlying principles, and to arrive at that state of understanding is not easy. This book was conceived and written in an attempt to clarify what is necessary theoretical equipment for anyone wishing to extract the maximum information from a magnetic resonance spectrum. It is also written for those who will find a fascination and great satisfaction in the way this subject, which involves so many sides of modern physics, holds together. It seems to the author, from experience, that the difficulty of getting to grips with the theory of magnetism and magnetic resonance is two sided. On the one hand one has forgotten, or never really known, the principles of electromagnetism on which it is based, and on the other, detailed analysis of the spectra requires a certain facility with the operator techniques of quantum mechanics. In both cases the principle difficulty appears to be unfamiliarity, so the chief aim in this book will be to introduce the enquirer to the relevent language in a reasonably connected fashion.
