Time-Resolved Resonance Raman Spectroscopy of Excited Triplet State All-Trans-Retinal: Excitation Profiles, Intersystem Crossing Kinetics, and O₂ Quenching

G. H. Atkinson¹and J. B. Pallix¹

Abstract

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) T₁ → S₀ 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.
