Spectroscopy of the Excited State e-bog

These proceedings report the lectures and seminars presented at the NATO Advanced Study Institute on "e;The Spectroscopy of the Excited State,"e; held at Erice, Italy, June 9-24, 1975. This Institute was an activity of the International School of Atomic and Molecular Spectroscopy of the "e;Ettore Majorana"e; Centre for Scientific Culture. The Institute consisted of a series of lectures on the spectroscopic properties of materials in excited electronic states, that, starting at a fundamental level, finally reached the current level of research. The sequence of lectures and the organization of the material taught were in keeping with a didac- tical presentation. In essence the course had the two-fold pur- pose of organizing what was known on the subject, and updating the knowledge in the field. The formal lectures were complemented by seminars whose abstracts are also included in these proceedings. The proceedings report also the contributions sent by Professors R.G.W. Norrish and S. C1aesson who, unfortunately, were not able to come because of illness. A total of 62 participants and 7 lecturers came from the following countries: Belgium, Canada, Czechoslovakia, France, Germany, Israel, Italy, Japan, Netherlands, Norway, Pakistan, Poland, Sweden, Switzerland, the United Kingdom, the United States and Venezuela. The secretaries of the course were: A. La Francesca for the administrative aspects of the meeting and P.Papagiannakopou10s for the scientific aspects of the meeting.
