Abstract : Absorption and emission spectra of p-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 can't explain the dual fluorescence without a twisting of the dimethylamino group. jg
