Fluorescence excitation spectroscopy of a cyanoanthracene (CNA) seeded in helium and expanded in a supersonic jet in the presence of 2,5-dimethyl-2,4-hexadiene (DMHD), reveals two types of transitions. One consists of narrow bands in both excitation and emission, characteristic of van der Waals comp

Fluorescence-excitation spectra and hole-burning spectra are recorded for jet-cooled complexes of anthracene with dimethylaniline (DMA) and dimethyl-ptoluidine (DMPT). The existence of isomeric forms (two in the first and three in the latter case) is evidenced. One of these forms (E form) showing br

The rotational-temperature dependence of the energy-resolved fluorescence, combined with the calculated level density, indicates that the large variations in the rate of the intramolecular vibrational relaxation over a small escess energy in Sr pcrylene is due to the fluctuations in the density of a
