Femtosecond transient stimulated emission pumping studies of ozone visible photodissociation

Abstract
We report a new variant of the femtosecond transition-state spectroscopy technique−transient stimulated emission pumping (TSEP). The initial application of TSEP to studies of ozone visible photodissociation indicates that the molecule is trapped in the Franck–Condon region for ∼90 fs. The wave packet then spreads along the reaction coordinate.
