Description

Molecular structure and character of intramolecular transitions in complexes of cadmium, zinc, mercury and lead with aminomethylene derivatives of 5-pyrazolethione were studied using the methods of luminescence and absorption electronic spectroscopy. It was ascertained that in diluted solutions of hydrocarbons and ethanol the coordination N→Cd-S is realized for cadmium complexes. In the series Zn-Cd-Hg internal effect of heavy atom was revealed, which stimulates only nonradiating transitions involving S1- and T-states

Abstract (Russian)

С использованием методов люминесцентной и абсорбционной электронной спектроскопии изучено молекулярное строение и характер внутримолекулярных переходов в комплесах кадмия, цинка, ртути и свинца с аминометиленовыми производными 5-пиразолтиона. Установлено, что в разбавленных растворах углеводородов и этанола для комплексов кадмия реализуется координация N→Cd-S. В ряду Zn-Cd-Hg обнаружен внутренний эффект тяжелого атома, стимулирующий только безызлучательные переходы при участии S1- и T-состояний
