INFRARED STUDY OF THE N—OH GROUP IN ALPHA AND BETA OXIMES

Abstract
The O—H bending and N—O stretching vibrations were studied in four pairs of isomeric oximes. A band at 1265 cm.−1, characteristic of the solution spectra of the α oximes, is identified with the O—H bending mode. Tentative assignments for the N—O stretching vibration both in solid and solution spectra are advanced. The β isomers show a distinct shift of the band associated with the N—O mode from about 950 cm.−1 in the solid to about 930 cm.−1 in solution.
