“…The triplets have similar lifetimes and reactivities but different energies, and there is therefore a systematic variation of the triplet properties. Some of the complexity of the relationship found by Hammond et al (1964) may be caused by the diverse properties of the sensitizers used. Another possible explanation is that the triplet energies we used were for the phosphorescence transition and not for the 0-0 band.…”

“…605nm, 46.5kcal/mol) (Gordon-Walker et al 1970) it can be seen that classical energy transfer from the flavin triplet to the c8-stilbene is unlikely to occur. To explain the sensitized isomerization of the cwa isomer one must postulate non-classical excitation and 'phantom triplets' (Hammond et al 1964). If one also postulated that the main decay to the ground state is from the 'phantom triplet' then the following scheme for the mechanism can be suggested, where Fs is the flavin excited singlet, F, c and t are the flavin, ci8- …”
