Extraction of Fast Changes in the Structure of a Disordered Ensemble of Photoexcited Biomolecules

Extraction of Fast Changes in the Structure of a Disordered Ensemble of Photoexcited Biomolecules

Using pump-probe experiments of varying time intervals between pump and probe, the method of time-resolved crystallography has given many insights into the fast time variations of crystallized molecules as a result of photoexcitation. We show here that quantities extractable from multiple diffractio...
