Photochemical reaction of full-aromatic β-carbolines in halomethanes 2. CHCl3: Electronic spectra and kinetics
The photochemical behaviour of full-aromatic β-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 β-carboline molecule to the chloroform molecu...
