Main description:

The Sixth International Conference on Time-Resolved Vibrational Spectroscopy was held from May 23 to 28, 1993 in Berlin, Germany. It continued the series of biennial conferences initiated in 1982 by Prof. George Atkinson (University of Arizona) at Lake Placid, USA, followed by conferences which were chaired by Prof. Alfred Laubereau (University of Bayreuth) and Dr. Manfred Stockburger (Max-Planck-Institut, G6ttingen) at Bayreuth-Bischofsgrtin, Germany, in 1985, by Prof. Joop D.W. Van Voorst (University of Amsterdam) at Amersfoort, The Netherlands, in 1987, Prof. Thomas G. Spiro (Princeton University) at Princeton, USA, in 1989, and by Prof. Hiroaki Takahashi (Waseda University) at Tokyo, Japan, in 1991. The Berlin conference attracted 120 participants from 19 different countries, representing the most active scientific groups of the world in this field. Since 1982 the field has benefited from the development of lasers with shorter pulses and of reliable tunable light sources in the infrared. Now, the main activities are focused on the primary photo-induced processes and their excited-state dynamics and on detailed investigations in photochemistry and photobiology. The high quality of the contributions given at this conference is reflected in this proceedings volume and will provide all scientists interested in this field with current state-of-the-art results.
