The absorption and induced circular dichroism (icd) spectra of the α-CD:DMABN system in water solution at 20 °C evidenced the presence of 1∶1 and 2∶1 complexes. The β-CD:DMABN system was found to be characterized by 1∶1 and 2∶2 associates.

Carbazole and α-carboline are the photocyclization products of o-nitrodiphenylamine and 3-nitro-2-phenylaminopyridine respectively. The proposed mechanism includes the transfer of the amine hydrogen to the nitro group, the abstraction of HNO2 and el

The study of the electronic absorption spectra of 4-aminoazobenzene subjected to an external electric field in nonpolar and polar solvents shows that the field-induced change in the absorption intensity is dominated by the solvent-solute interaction.
