Pyrrole studies. IX. The infrared spectra of 1-substituted pyrroles

Abstract

The positions and intensities of the characteristic infrared absorption bands of the pyrrole nucleus in the region 2000-600 cm^-1 of 45 1-substituted pyrroles, 2,5-dimethylpyrroles, and 3,4-dimethylpyrroles are recorded and discussed.
