The Raman effect is a most useful tool for the study of molecular vibrations and molecular structure. Information about the structure and symmetry of molecules, as well as about their vibrational energies can be obtained to a reasonable degree of satisfaction from their infrared and Raman vibrational spectra. The body of knowl edqe of the vibrational infrared and Raman spectra of molecules is immense and is now so well organized and understood that it is found to be represented in any stan dard upper level undergraduate curriculum in chemistry. The rotational energies of a molecule and quantitative details about its structure can only be obtained through the techniques of microwave, and high...
Competitive binding techniques such as radioimmunoassay (RIA) are widely used to measure an enormous variety of compounds in biological fluids. Current methods have 1 2 arisen from the pioneering work ofYalow and Berson in the U. S. A. and Ekins in the u. K. Much of the early development was concerned with the analysis of protein hormones, and nearly a decade passed before attention focussed also on small molecules such as steroids and drugs. The potential of immunoassay methods for drug monitoring in clinical and forensic laboratories and in addict treatment programmes resulted in the commercial production of immunoassays for various therapeutic and abused drugs, making the technique availa...

Zeolites and zeolite-like microporous materials have been playing an ever-increasing role in heterogeneous catalysis for more than three decades. An impressive number of large-scale industrial processes in petroleum refining, petrochemistry and the manufacture of organic chemicals are nowadays carried out using zeolite catalysts, and the future of zeolites in industrial catalysis continues to be bright. Authored by an international team of renowned scientists, the seven chapters of this book present a comprehensive overview of the application of zeolites in industrial catalysis, while also providing a true scientific understanding of how zeolites are synthesized, modified and characterized, and putting special emphasis on shape-selective catalysis, which is a unique feature of zeolites.
Energy will be a most important topic in the 1980s. The speed with which a dozen or more trends will develop will be critical. Most of these trends are interdependent and interacting, and include: - the degree of constraint on oil and gas supplies exercised by the producers, whether inside or outside the OPEC, as they each attempt to match produc tion to their own energy needs and the funding of their own economic growth from exports, - the depth of the appreciation by industrialized countries that energy supplies will be tight and fossil fuels will be very expensive at least until the end of the century, - the actions taken by those countries to ameliorate this situation, in exploration for...
