✦ Synopsis

We report results of 1 H NMR measurements of proton mobility in a-, b-, and c-polymorphs of glycine, including the energy barriers and specific correlation times for the amino group reorientation process. We discuss relations between second-order phase transition in b-glycine observed at 252 K and proton mobility in b-glycine crystals.
