Електронна абсорбційна спектроскопія бензімідазольних аналогів халкону
Анотація
В рамках наближення ESSA проведений теоретичний аналіз електронних спектрів поглинання бензімідазольних аналогів халкону. Показано, що вплив бензімідазольного фрагменту на спектри відповідних аналогів халкону обумовлений посиленням донорно-акцепторної взаємодії в їх молекулах при переході до збудженого стану за рахунок введеного гетероциклу.
