[en] The strong absorption band at 710 nm in an irradiated naphthalene crystal was studied at 4.2 K. Evidence from the deuterium shift, the absorption spectrum in a 50:50 C10H8-C10D8 crystal, and the fluorescence spectrum indicates that the radical responsible for 710-nm absorption is the 1-hydrobinaphthyl radical. This radical is formed through the bimolecular reaction between a naphthyl radical and a naphthalene molecule and is stable at room temperature in the crystalline lattice. 3 figures, 2 tables

[en] Absorption and laser-induced fluorescence of phenylcyclohexadienyl radicals in an irradiated biphenyl crystal have been measured at 4.2 K. The origin of the lowest electronic transition of the radical is located at 6604 A. It was shown that the radical produced in the irradiated crystal is most probably a 2- or 4-hydrogen adduct radical, a phenylcyclohexadienyl radical, from the analysis of the vibrational frequency, from an ESR spectrum, and from the results of SCF-CI MO calculation

[en] A theory has been described of solvents effects on radiative rate constants using first-order perturbation theory with vibrionic coupling along with solvent-dependent energy denominators. The fixed expression of this theory contained no provisions for solvent effects on the wave functions. However, if all decay channels are properly taken into account, the direct solvent contribution to the radiative rate constant should be nonzero
