Abstract
The i.r. spectra of 3-chloro-, 3-bromo- and 3-iodothiophene as liquids and solids at 100 K have been studied from 4000 to 250 cm −1. The laser Raman spectra of liquids have also been recorded and depolarization values have been measured. An assignment of the 21 fundamental vibrations is proposed based on group frequency correlations, Raman polarization data and comparison with the spectra of parent molecule.
