Abstract

Ultrafast trans-cis photoisomerization in DCM solutions has been investigated using new time-resolved Raman spectroscopy. The new method measures stimulated Raman scattering in photoinduced transient species using a Raman pump pulse with narrow bandwidth and a femtosecond supercontinuum probe pulse. The temporal and spectral resolutions obtained in this study are 250 fs and 25 cm-1, respectively. The observed Raman signals are separated to two groups from the temporal dependence and assigned to an intermediate state between trans- and cis-forms and a charge-transfer state in DCM.
