Infrared spectra of nitrogen adsorbed in NaA zeolite. Experimental determination of electrostatic field in the cavities from induced band intensity and comparison with theoretical results

Abstract

The integrated intensity A of infrared forbidden bands is related to the field E which induces the band. We present the relations between A and E in the case of rotating and oriented molecules, and we analyse the induced spectrum of N₂ adsorbed in NaA. The field value obtained by means of the band intensity is compared with theoretical values.
