摘要：

The effect of hydrostatic pressure up to 4 kbar on the low frequency Raman spectrum of hydrogen bonded (formamide, N-methylformamide, N-ethylformamide, and N-methylpropionamide) and nonhydrogen bonded (N,N'-dimethylformamide and N,N'-dimethylacetamide) liquid amides is reported. A shift of ca. 4.0 cm-1/kbar is observed for the nonhydrogen bonded amides: For the hydrogen bonded amides the shift is ca. 2.0-3.0 cm-1/kbar. The difference may be explained by the compression of the hydrogen bond which affects the librational motion of the molecules.
