A mode-locked dye laser is used to generate the S+J TPF pattern of azulene and some of its derivatives. Since none of the patterns shows a Iarger width at half maximum than the one obtained with dimethyl-POPOP, a lifetime of less than 1 ps has to be postulated for 'the excited vlbronic levels Sr,, o

Relaxation processes of the singlet excited states of carotenoids containing a carbonyl group were investigated in relation to the molecular structure around the carbonyl group. The relative quantum yield of fluorescence from the allowed Sz state to the forbidden S, state follows the energy gap law
