Abstract
The photoisomerization of cis- and trans-stilbenes adsorbed in zeolite supercage was studied by means of Raman spectroscopy for in situ anal ysis of the isomer ratio in the photostationary state. It was found th at the isomerization proceeds mainly through the singlet excited state s for NaY and triplet excited states for KY, and also a new potential energy surface for the photoisomerization was proposed.
