Excited Triplet

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.

The article traces the development of the epr and optical spectroscopic characterisation and progressive theoretical understanding of the aryl cation, starting from the initial cryogenic epr study of 2,5-dialkoxyl-4-morpholinophenyl cation, which defined unambiguously its triplet state character, through simple MO, ab initio and DFT calculations on substituted aryl cations, to picosecond laser photolysis studies in fluorinated solvents, noting especially the early and vital contribution of Martyn Symons.
