Nuclear magnetic resonance of glycine in aqueous solution

Abstract

Relaxation time measurements as a function of the pH and the temperature are performed in ¹⁴N and ²D in an aqueous solution of glycine. Information about the nitrogen quadrupole interaction and the correlation times involved is obtained; the quadrupole interaction in NH₂–CH₂–COO⁻ is 3.48 MHz and the correlation time τ_q=6.18×10⁻¹² sec.
