摘要：

The photochemical behaviour of full-aromatic beta-carbolines (nor-harmane, harmane and harmine) in chloroform medium and the corresponding UV absorption and fluorescence emission spectra are discussed. Irreversible electron transfer from the singlet excited beta-carboline molecule to the chloroform molecule in the transient excited charge transfer complex has been proposed as the primary photochemical process initiating the mechanism of secondary reactions in this system. The results obtained are interpreted in terms of a diffusional quenching mechanism and are compared with those obtained using different halomethanes.
