Transient resonance Raman spectra of T, benzophenone (BP) and its cal-bonyl-'KO-substltuted analogue were measured with 355 nm excitation which is in rcsonancc with a triplet-triplet (T,,.+T,) transition in the ultraviolet. The intensity of the CO stretch band was greatly enhanced under this resonan

โฆ Synopsis
Triplet-triplet
absorption spectrum of benzophenone was obtained between 300 and 600 m/l by the flash photolysis at room temperature.
The spectrum evidently resembles that of the ketyl radical.

An inversion scheme to obtain excited-state potential energy surfaces from experimental absorption spectra is presented. The scheme is based on simulating the quantum dynamical processes with high accuracy. A modification of the simulation enables analysis of regions in the potential which the absor
