The S I state of jet-cooled 4-(N,N-dimethylamino)-4'-cyanostilbene (DCS) was studied by picosecond fluorescence spectroscopy. The line structure of the S O -\* Sl-excitation spectrum is a superposition of transitions characteristic of isolated trans-sti~bene and the dimethylamino group. Rotational c
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
Laser fluorescence excitation spectra and dispersed fluorescence spectra of jet-cooled 3-bromotropolone and its OD derivative have been measured in the &-So region to investigate the intramolecular hydrogen bond. Only one electronic origin band has been detected, although two tautomeric forms are po
