Abstract

A detailed analysis of photo-stimulated structural transitions plays an important role in studying of organic molecules. This problem can be successfully solved by using optical methods since both linear and non-linear properties of organic molecules strongly depend on their structure.1 Recent progress in the field of short laser pulse generation in pico- and femtosecond range2 makes it possible to obtain detailed information on the structural dynamics of macromolecules.3 The computer molecular dynamics (MD) simulation method47 enables one to interpret the experimental information available and in many cases, to deepen and broaden understanding of the physics of processes taking place in molecules. We report here on the MD study of the structure dynamics of a stilbene molecule excited by a laser pulse.8 Note, that the molecule of stilbene which was studied experimentally in detail3' 10 13 is of particular interest being a simple model for studying the mechanism of laser-induced molecular photoisomerization.
