The time-resolved resonance Raman (TR3) spectra of excited triplet state all-trans-retinal (ATR (T1)) are analyzed with respect to (1) time-resolved excitation profiles (TREP), (2) T1S0 intersystem crossing rates, and (3) O2 quenching kinetics. These TR3 data are used to comment on the electronic characteristics and kinetic decay of the excited triplet state of a specific retinal isomer in room temperature solutions.
