Good Agreement

Several salts of trimethylamine oxide have been prepared. A species common to all these salts, the (CH3)3NOH+ ion, has been inferred from the infrared spectra of the solids, but with varying degrees of interaction in the hydrogen bond [Formula: see text] depending on the anion. These variations have been investigated in detail, and with the help of deuterium replacement, confident assignments for the OH stretching, bending, and torsional modes have been made. A splitting of about 80 cm−1 in the bending mode has been noted, and has been ascribed to correlation field coupling. With one exception, the assignments are in good agreement with those previously determined by Giguère and Chin.

Local Mode Analysis

The polarized crystal spectra of M2MnCl4•2X2O (M = Cs, Rb; X = H, D) have been measured at 10 K in the near-infrared region. The data have been analyzed using a local-mode model that includes the bending mode. The resulting parameters are related to hydrogen bonding in the crystals. The spectra of partially deuterated species show a large number of bands due to HOD vibrations. The parameters from these spectra are compared to those from the H2O and D2O spectra. Arguments as to the importance of Fermi resonance in these spectra are presented. Key words: near-infrared, single crystal, hydrogen bond, Fermi resonance.
