Abstract:

Low-frequency vibrations of l-histidine in a neat solid state and its monohydrochloride monohydrate are both investigated using THz spectroscopy and DFT calculations. The molecular motions in those modes are further quantitatively decomposed into a number of submotions and discussed in terms of their contributions to a mode. The results show significant differences in the averaged contribution percentage of intermolecular motions and the dihedral angle distortions of the imidazole ring between these two crystals. Those phenomena are interpreted from the viewpoint of their hydrogen-bond configurations.
