Infrared and Raman spectra of histamine-Nh(4) and histamine-Nd-4 monohydrochlorides

The infrared and Raman spectra of histamine monohydrochloride and its N-deu terated derivative as solid samples were recorded. The data obtained were a nalyzed from the crystal structure. A general assignment of the fundamental vibrational modes was proposed on the basis of the measured isotopic shift s and correlations with previous data reported for imidazole and related mo lecules. The results are consistent with the interactions between adjacent molecules present in solid state. Copyright (C) 1999 John Wiley & Sons, Ltd .
