Proton and Deuteron Magnetic Resonances in Glycine Compounds

Abstract

Proton and deuteron magnetic resonance have been studied at different temperatures in partially deuterated glycine and its addition compounds. The results quantitatively confirm the zwitter ion nature of glycine. The linewidth transitions in G₃H₂SO₄ and G₂HNO₃ indicate the presence of two kinds of NH₃ groups, one reorienting fast and the other slow.
