Far Infrared Spectra

The far-infrared spectra of thin films of NH4F and ND4F and the Raman spectra of polycrystalline samples of both compounds have been recorded at −170°C. Two low-frequency lattice vibrations were observed in each spectrum and these have been assigned as optical translations on the basis of their isotopic shift factors. Librational modes were not observed in any of the spectra.

The low frequency infrared spectra from 450 to 75 cm−1 of seven oximes and five aldoximes have been recorded for pure samples and for dilute solutions in cyclohexane. An intense characteristic band is present in the solution spectra at 367 ± 10 cm−1. This characteristic band shifts to 275 ± 10 cm−1 in the spectra of the OD compounds. The 367 ± 10 cm−1 and 275 ± 10 cm−1 bands are assigned to OH and OD torsional vibrations. A comparison of the solution spectra with spectra of the solid samples indicated that the OH … N hydrogen bond stretch of oximes and aldoximes occurs in 300 to 200 cm−1 region. Strong bands also are present in 140 to 100 cm−1 region which are due to OH … N bending modes or perhaps lattice vibrations.
