摘要：

Time-resolved resonance Raman (TR3) spectroscopy was used to monitor the photolysis of the dianion of (trans-stilbene (T2-) induced by pulsed laser excitation at 532.0 nm. Reaction times were between 2 and 500 μs. A short-lived intermediate formed in the photolysis was identified by its TR3 spectrum as the trans-radical anion of stilbene (T-). The reformation of T2- from T- was qualitatively monitored by TR3 spectroscopy and found to be completed in less than 300 μs. © 1979.
