TLDR
The infra-red spectra of six pyrones and pyrthiones in the region 2000-800 cm −1 are discussed and tentative assignments for most of the bands are suggested by analogy with other heteroaromatic compounds.About:

The carbonyl stretching bands in the infrared spectra of unsaturated lactones
TL;DR: In this paper, the authors observed that unsaturated lactones exhibit two bands in the region of the spectrum associated with the C=O stretching vibrational mode, which is observed both in the infrared and Raman spectra.
