Abstract

It has been shown that in the IR spectrum of d3-acetonitrile adsorbed on various zeolite catalysts, the values characterizing the absorption bands in the ν(C≡N) range, namely their absorbances (together with their positions and thermal stabilities) may represent a relative measure for the concentration and the strength of their proton donor and electron acceptor centers.

Abstract

Показано, что в ИК-спектрах ацетонитрила-d3, адсорбированного на различных цеолитных катализаторах, величины, характеризующие абсорбционные полосы в области ν(C≡N), а именно их абсорбции (вместе с их расположением и термической стабильностью) могут служить относительной мерой концентраций и сил их протоно-донорных и электроноакцепторных центров.
