โœฆ Synopsis

Kcccivcd 3 .I une 1983 The S;t -So fluorccccnce spectra and qusntum yields and the .Sz lifetimes of ~.~,3,3-tctr~metily~ind~nethione (TUIr) ha&e been mca.urcd in several sotventc using a synchronously pumped picosecond dye laser excitation system. The S, nonradhtkc decay rate is ntsrkedi) sohent dcpendcnt. In inert perfhxoroalkane solvents remarkably large &-So fluorescence quantum yields (of = 0.14) .md long S, lifetimes (T= 880 ps) are measured. Hydrocarbons are effxient excited-state quenchers.

Fluorescence has been observed from the second excited singkt stste of tkiophosgene vapour. The emission is excited mainly by transitions originating in the out-of-plane bending mode of the ground stzte and terminating in the lowest vibrational levekof the-excited state. i '.

The dynamic behavior of the second excited singlet state of QCS has been investigated for the first time in liquid solutions. In perfluoroalkane solvents strong B-ji. fluorescence (@f up to 0.077) 1s observed when the molecule is excited to bound vibrational states. s lifetimes of up 10 2.8 ns are o
