摘要：

Two regression dependences of the energy of the intramolecular charge-transfer transition in 1-ethyl-2-formylbenzimidazole on the polarity and polarizability of the medium have been established; one relates to the syn-periplanar conformer and the other, to the anti-periplanar conformer. The different solvatochromism of the two molecular forms is associated with the different sensitivity of low-energy electronic transitions of these conformers to nonspecific solvation.
