N-methylbenzanilide was found to exhibit fluorescence in the 500-nm region, and the uv-absorption spectrum showed moderate to strong adsorption starting at 310m. It is thought that the long fluorescence band at 610nm must result from an intramolecular charge-transfer transition which involves the whole molecule. The excitation is attributed to an indirect relaxation mechanism, which involves internal torsion and dielectric relaxation. Strongly dipolar solvents were found to quench the fluorescence at 510nm. 10 refs., 2 figs.
