A weak transient fluorescence (&f \* 0.0036 and r = 27 ns) has been detected by employing single photon counting methods from solutions of anthracene, 6.7X low5 M, and trans.trans-2,4-hexadiene, 1.76 M. This emission is tentatively assigned to the anthracene/l,3diene exciplex and appears to confirm

The fluorescence lifetime of xuleneda is found to be longer than that of azulenef?e both in frozen scluticn and under collision-free condition in the vapour. The lifetime of the emission of the isolated molecule decreases with higher energy excitation.
The vibronic sequences shown by the SI+So spectrum of biphenylene have been calculated by means of the relevant vibronic coupling and Franck-Condon factors. The results of our calculations make it possible to identify the bzu modes and a, modes responsible for the spectrum and involved in the radiat
