โœฆ Synopsis

The fluorescence from the second excited singlet state of pyrene and 3.4~benzpyrene in the vapour phase has been observed. The effect of inert gas, temperature and excitation frequency has been investigated. The estimated rate constants for the internal conversion and the reverse process far pyrene are 2 x 1012 s-l and lo7 s-l respectively.

The emission spectra of the second excited singlet state of [ 181 annukne and of monofluoro [ 181 annulene (m a 3methylpentanc glass at 4 K) are reported. The large ener,7 gap between the fist and second excited singlet states inhibits fast internal cogversion and favours the appearance of S2 + So e

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 '.
