Rydberg Series in Atoms and Molecules deals with the Rydberg states of atomic and molecular systems. Rydberg series in atomic spectra and of diatomic molecules are examined, along with Rydberg terms of polyatomic molecules such as hydrocarbons with triple bonds, hydrocarbon molecules with double bonds, and benzene and benzene derivatives. Comprised of four chapters, this book begins with an overview of the spectrum of the hydrogen atom, along with some elementary and useful concepts and definitions. Some difficulties in the classification of excited states of simple molecules into Rydberg and non-Rydberg states are highlighted. The next chapter considers Rydberg series in atomic spectra and theoretical methods for quantitative description of atomic structures. One-electron models for Rydberg terms are also described, together with Rydberg series of diatomic molecules such as N2 and O2, CO and NO, and bromine and iodine. The final chapter is devoted to Rydberg terms of polyatomic molecules including hydrocarbons with triple and double bonds; benzene and benzene derivatives; hydrides with central atom; saturated hydrocarbons; and aldehydes and ketones. This monograph is written primarily for both students and nonspecialists.

The ICMS Workshop on Geometric and Combinatorial Methods in Group Theory, held at Heriot-Watt University in 1993, brought together some of the leading research workers in the subject. Some of the survey articles and contributed papers presented at the meeting are collected in this volume. The former cover a number of areas of current interest and include papers by: S. M. Gersten, R. I. Grigorchuk, P. H. Kropholler, A. Lubotzky, A. A. Razborov and E. Zelmanov. The contributed articles, all refereed, range over a wide number of topics in combinatorial and geometric group theory and related topics. The volume represents a summary of the state of knowledge of the field, and as such will be indispensable to all research workers in the area.

The volume starts with comparative reservoir limnology and deals with problems relating tropical, semi-arid and temperate reservoirs. The second part concerns mathematical models of reservoirs, including new techniques for investigating their limnology. These cover physical, chemical and biological phenomena, remote sensing and the use of modelling to establish the most efficient strategy for water quality sampling. In the third part, on reservoir water quality management, the potential available in fish population management for biomanipulation of reservoir water quality is introduced. Also included is a valuable section on a wide range of water quality measures, coming from the well-known Czech hydrobiological laboratory. Finally the editors summarize the present state of reservoir limnology. This book should be of interest to hydrobiologists and aquatic ecologists, reservoir and sanitary engineers, fisheries officers, postgraduate teaching, and the water industry dealing with drinking water supply and will provide insight into regulated rivers. It draws information from all over thye world and is relevant to the whole world.
