摘要
The application of time-resolved x-ray diffraction for monitoring large amplitude coherent intramolecular vibrations in a molecular crystal is considered. The coherent vibrations are induced in the electronically excited state by an ultrashort optical pump pulse and the x-ray diffraction intensity based on a model crystal consisting of diatomic molecules is derived. Time-resolved diffraction signals are calculated for an iodine molecular crystal. (C) 2005 American Institute of Physics.
