The dipole moment derivative of the hydrogen bond in ice has been calculated assuming that the molecules can be represented as non-overlapping polarizable charge distributions characterized by dipole and quadrupole moments. The value is 0.1 electron charges which is about one third of the experimental value obtained from the far-infrared spectrum. The model predicts therefore only about one tenth of the experimental integrated intensity from which the effective charge was derived. Most of the intensity must therefore be due to specific hydrogen-bond interactions.

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.
