Popis:	Infrared and FT-Raman spectra of both deuterated and undeuterated tetronic acid have been examined. The enol form predominates in the solid form, but some keto form is apparent in the spectra. Reported here are the tentative assignments for all bands observed from 4000 to 200 cm −1 . Group frequencies obtained by comparing the spectral data acquired with vibrational assignments of similar compounds by other investigators were used to aid the assignment. The spectra are consistent with a C S point group, indicating the structure of tetronic acid to be planar in the solid state.
