The time-resolved resonance Raman (TR 3 ) spectra of excited triplet state all-trans-retinal(ATR (T 1 )) are analyzed with respect to (1) time-resolved excitation profiles(TREP), (2) T 1 → S 0 intersystem crossing rates, and (3) O 2 quenching kinetics. TheseTR 3 data are used to comment on the electronic characteristics and kinetic decay ofthe excited triplet state of a specific retinal isomer in room temperature solutions.
