Аннотация:The development of ultrashort light pulses during the last decade has opened the way to the direct probing of the fundamental dynamic processes of molecular systems. Coupled with the huge strides made in handling complex, many-body systems by computer simulation and the continued development of molecular theories, the availability of these ultrashort lased pulses has allowed our understanding of reaction dynamics and their subtleties to flourish. Our goal is to achieve a high level of predictability concerning the dynamic behavior of molecular systems in a broad range of disordered environments. However, the individual approaches to this goal—that is, the ways in which the fundamental scientific issues of molecular dynamics are studied—have varied.
