✦ Synopsis

The incoherent ineleastic neutron scattering spectra of single and polycrystal samples of potassium hydrogen (deuterium) malonate have been obtained. These spectra have been assigned in concordance with optical spectra except for the location of the antisymmetric hydrogen bond stretch v,(OHO) which we observe at 470 cm-'. The corresponding band in the spectrum of the deuterated sample occurs at 411 cm-r. The CO* scissoring mode was also observed with significant intensity. These results are interpreted as a mixing of the two modes. This explains the rotation of v,(OHO) displacement vector. This vector lies, not along an 0 . . . 0 direction, but along a C . . . C direction.

Inehstic neutron scattering spectra of KHCO3 and CsH(NO& have been obtained in the region 400 -. 2400 and 400 -+ 2800 cm-' respectively\_ The in-and out-ofqhase bending vibrations of the hydrogen bonds have been observed and assigned. For CsH(NO& the two bending modes are closer in frequency than in
