Femtosecond fluorescence study of the reaction pathways and nature of the reactive S1 state of cis-stilbene
Abstract
We report a femtosecond time-resolved fluorescence study of C bond, while the second component is the fluorescence from the substantially twisted region around a shallow S1 potential minimum. The quantitative analysis of the femtosecond fluorescence data clearly showed that the whole isomerization process proceeds in the one-
C–Ph skeletal structure. On the basis of the results obtained, we discuss the dynamics and mechanism of the isomerization/cyclization reactions of
