The rate constants of fluorescence quenching of the acridizimum ion by alkyl bromides and iodides are determined by the donor behaviour (ionization potectial) of the quenchers. An encounter-CT complex is postulated, in which the quencher acts as an electron donor.

The quenching constants K and the rate constants k of the heavy-atom-induced fluorescence quenching of B-methyltcridone were obtained from Stern-Volmer plots for nine different solvents. Iodomethane, iodoethane, iodobutane and iodobenzene were used as quenchers. It was found that the solvent depend

The fluorescence lifetime, rf, of 9-cyanoanthracene (9CNA) in the supercritical fluid (SF) of Xe (6.8 MPa at 293 K) is found to be 2.39 \_ 0.13 ns, which is much shorter than the 17.78 \_+ 0.43 ns measured in SF of CO 2. This large decrease in Tf is interpreted in terms of the vibronic-level-depende

Solutions of benzene in 02 free cyclohexane gave on illumination at 2.54 nm tluorescence yields which were Lower rip nit;,ctintly in the presence of Xe, than in its absence. The photochemicd yield of benzvdene was unaffected. The results support the assumption that :his photochemistry originates in
