Abstract

The terahertz waves have been applied to the spectroscopy of molecular crystals. The group based on hybrid organic–inorganic crystals like triglycine zinc chloride, triglycine sulphate, triglycine selenate, diglycine hydrobromide, diglycine hydrochloride, diglycine lithium nitrate, glycine lithium nitrate has been considered. The dispersion relation phonon–polariton have been shown between 10 cm−1 and 80 cm−1 for diglycine lithium nitrate, triglycine zinc chloride, and diglycine hydrobromide.

This study was performed using TeraView's TPS spectra 3000 system. (TeraView, Cambridge, UK)
