✦ Synopsis

A self-consistent reaction field (SCRF) method is used to calculate the absorption and emission spectra ofp-N,N-dimethylaminobenzonitrile (DMABN) and 6-cyanobenzquinuclidine (CBQ) in different solvents. The dual fluorescence of DMABN is discussed in terms of internal twisting of the excited state as well as in terms of N-inversion of the dimethylamino group. The results indicate that the N-inversion mechanism cannot explain the dual fluorescence without a twisting of the dimethylamino group.

The dual luminescence of 4-N,N-dimethylaminobenzonitrile (DMABN) has been observed in 1-fluoropentane; only the normal emission is observed in hexane and in perfluorohexane. The solvent does not form exciplexes with DMABN and acts only by its dielectric stabilization of the twisted rotamer of DMABN.

The first excited singlet state, an intramofecular charge transfer state, of p-N,N-dimethylaminohenzonitrile (DhWBN) is quenched by tertiary amines. The quenching rate cannot be correlated with the oxidation potential of the amines, but is conrrolled by the size of the amme alkyl group. This unusual
