Abstract

Recent advances in generation of pico- and femtosecond laser pulses make it possible to study chemical events in real time by using pulses shorter than or comparable to molecular vibrational periods. Specifically, by using an apparatus with a time resolution of 10 fs Schoenleitn et al.[1] have sutdied the cis-trans isomerization in rhodopsin and have found that the first step in vision occurs on a 200 fs time scale. However, understanding of the dynamics of this isomerization remains a fundamental problem in photochemistry and biology.
