Abstract
1. The frequencies and total absolute intensities of the infrared spectrum absorption band of the C=O groups were determined for a number of mono-and diacylated thiophene homologs and esters of thiophene mono-and dicarboxylic acids. 2. An approximate calculation was made of the angles of emergence of C=O groups from the plane of the thiophene ring. 3. The frequencies and total absolute intensities of C=O groups were correlated with the position and nature of the substituent groups
