Femtosecond laser study of energy disposal in the solution phase isomerization of stilbene

摘要

Femtosecond laser studies ofcishyphen;stilbene isomerization show the absorption of the hottransproduct decaying in 20 ps. An initial internal temperature of 725plusmn;100 K is estimated which decays with a ca. 14 ps time constant. This temperature accounts for less than onehyphen;half the photon energy implying significant energy loss by solvent friction.
