Abstract
Time-resolved resonance Raman (RR) spectra of the excited triplet state T1 of 2,2'-bipyridine (BP), 2,2'-bipyridine-3,3'-diol BP(OH)2, and 5,5'-dimethyl-2,2'-bipyridine-3,3'-diol Me2BP(OH)2 are obtained. and interpreted by comparison with their ground-state Raman spectra and the T1 spectrum of biphenyl.
The BP T1 RR spectrum is assigned assuming C2h molecular symmetry. The T1 RR spectra of BP(OH)2 and Me2BP(OH)2 are ascribed to diketo tautomers that are products of double proton transfer in the S1 state.
