The Spectra of the Dicyanobenzenes

Abstract

<p>This work is concerned with the assignment of the fundamental frequencies of the three dicyanobenzenes (para-, meta- and ortho-) and their deuterated species using infrared data for the region 4000-30 cm‾¹ and Raman spectra, and interpretations are given for all the observed bands not chosen as fundamentals.</p> <p>From a comparative analysis of the spectra, together with those of other related molecules assignments have been made for the 36 normal frequencies of vibration of the molecules.</p> <p>The assignments for these compounds constitute the basis for the interpretation of the spectra of more complex and less symmetrical disubstituted derivatives.</p>
