✦ Synopsis


Raman scattering measurements have been carried out on a single crystal of a-glycine in the temperature range 83-360 K. The observed splitting of the NH 3 + torsional mode in the temperature range 83-313 K shows that NH 3 + torsional motion is non-degenerate even at ambient conditions. The stiffening of the N + H stretch mode on increasing the temperature from 120 to 360 K suggests increase in the inter-layer hydrogen bond length with temperature.
