The ene10sed ~roeeedings of the NATO Advaneed Study Institute held in September 1979 are intended to provide a eomprehensive introduetion to the development of semie1assiea1 methods for mo1eeu1ar seattering and speetroseopy over the past twenty years. Progress in the seattering field may be taken to date from the famous paper by Ford and Wheeler in 1959, and eoineidenta1ly the RKR teehnique for diatomie speetroseopy was rediseovered at roughly t~e' same time. Subsequent developments have e~hasised the insight to be gained by eombining elassica1 and quant~ meehaniea1 ideas in a wide variety of...

It is general consensus that Combinatorics has developed into a full-fledged mathematical discipline whose beginnings as a charming pastime have long since been left behind and whose great signifi- cance for other branches of both pure and applied mathematics is only beginning to be realized. The last ten years have witnessed a tremendous outburst of activity both in relatively new fields such as Coding Theory and the Theory of Matroids as well as in' more time honored endeavors such as Generating Functions and the Inver- sion Calculus. Although the number of text books on these subjects is...

This volume contains lectures given at the NATO Advanced Study Institute on Long-Time Predictions in Dynamics conducted in Cortina d'Ampezzo, Italy during August 3-16, 1975. The lectures were presented in groups, according to the original structure of the Institute. Under "Fundamentals" the general concepts were treated by Contopoulos, DeWitt, Reichl, Stiefel, Szebehely, Bartlett, Kirchgraber, Verhults and Sigrist. This was followed by the series of lectures on "Numerical and Statistical Analysis" offered by Aarseth, Baumgarte and Tapley. The third principal subject was "Three and Many-Body...

For Louis Pasteur, the two distinctive properties of dissymmetric systems, optical activity and chiral discrimination, provided prime evidence for a Divine origin to the universe. Handedness appeared to be built into the macrocosm of the galaxies, each with a non-superposable mirror image by virtue of its rotation, as well as the microcosm of each molecule of most natural products. The best that the chemist in the laboratory could accomplish appeared to be the synthesis of the detordu internally-compensated meso-form and, as Pasteur ultimately came to admit, the externally-compensated...

This volume is based on lectures and discussions presented at a NATO Advanced Study Institute on ELF and VLF Radio Wave Propagation, which was held in Norway April 1974. The study of propagation of electromagnetic waves with frequen- cies below 100 kHz has long traditions in ionospheric physics. To-day, this frequency range is still of great importance, both to the physicist, who uses the waves as diagnostic tools to study the earth's environment and to the engineer who exploits the characteris- tics of these waves to improve communications, navigation and timing systems. In recent years the...

The present volume collects lecture notes from the session of the International School of Mathematical Physics 'Ettore Majorana' on Renormalization Theory that took place in Erice (Sicily), August 17 to August 31, 1975. The School was a NATO Advanced Study Institute sponsored by the Italian Ministry of Public Education, the Italian Minis- try of Scientific and Technological Research, and the Regional Sicilian Government. Renormalization theory has, by now, acquired forty years of history. The present volume assumes a general acquaintance with the elementary facts of the subject as they might...

During a NATO Advanced Study Institute in Izmir, Tur key, July 1973 on Modern Developments in Engineering Seis mology and Earthquake Engineering it emerged that a debate on Continuum Mechanics Aspects of Geodynamics and Rock Fracture Mechanics would be very welcome. Therefore, it was decided to seek NATO sponsorship for an Advanced Study In stitute on this subject. The purpose of the new Advanced Study Institute was to provide a link between mechanics of continuum media and geo dynamic s. By bringing together a group of leading scientists from the above two fields and participants actively...

This book contains the transcripts of the lectures presented at the NATO Advanced study Institute on "Computational Techniques in Quantum Chemistry and Molecular Physics," held at Ramsau, Germany, 4th - 21st Sept. 1974. Quantum theory was developed in the early decades of this century and was first applied to problems in chemistry and molecular physics as early as 1927. It soon emerged however, that it was impossible to con- sider any but the simplest systems in any quantita- tive detail because of the complexity of Schrodinger's equation which is the basic equation for chemical and molecular...
