Abstract
The spectra of several isomeric oximes in the solid state were examined in the range 700–3600 cm−1. The associated OH stretching frequency near 3250 cm.−1 in the α oximes is displaced towards lower frequency in the β oximes. The region of the OH stretching mode of several oximes was also studied in benzene and chloroform solutions. The frequencies near 1300 cm.−1 and 920 cm.−1are tentatively assigned to the OH deformation and the N-OH stretching modes, respectively. No consistent differences are observed between the α and the β oximes with respect to these vibrations. The band at approximately 1640 cm.−1 ascribed to the C==N vibration remains essentially unchanged in the spectra of the two isomeric forms.Keywords
