The intensity decrement in fluorescence and triplet-triplet absorption spectra of 9, IO-dichloroanthracene (DCA) by amine in acetonitrile is interpreted in terms of the quenching of the lowest excited singlet state ('DCA(S,)) of DCA by amine, and the DCA radical anion produced via the singlet excipl
The rate of formation of the intramolecular charge-transfer state of 4-(N,N-dimethylamino)benzonitrile (DMABN) has been determined in supercritical CFsH using a fast single-photon counting technique. The rate constant increases rapidly with increasing CFIH density, indicating the importance of the p
