Transient Resonance Raman Spectra of Michler’s Ketone in the Lowest Excited Triplet State

Abstract
Transient resonance Raman spectra of Michler’s ketone in the lowest excited triplet state were measured in ethanol and benzene. The spectral features of the T1 state in these solvents were similar to each other although some frequency shifts were observed. This result suggests that Michler’s ketone retains a charge transfer T1 state in nonpolar solvents as well as in polar solvents.
