摘要：

The IR spectra of a number of imidazole derivatives were studied in the solid state at room and liquid nitrogen temperatures. The bands ascribed to stretching and out-of-plane deformation vibrations of NH groups involved in strong NH...N hydrogen bonds were analysed. The energy of this bond reflected in the position of the nu(NH...N) band changes over a broad range so that it was possible to investigate band shaping due to the overlap with the overtone band of the gamma(NH...N) mode. The correlation between the gamma(NH...N) and nu(NH...) frequencies shows that the gamma(NH...N) value for strong NH...N bridges only slightly depends on nu(NH...N).
