A study of NMR relaxation on binary mixed solvent

Abstract

NMR relaxation reveals information on structure and dynamic properties of liqs. According to the theory of Brownian motion and NMR relaxation for a nucleus with spin >1/2, the reorientational correlation time of a mol. in a liquid can be evaluated from the relaxation time of the quadrupolar nucleus. The relaxation time of 2H and 14N in a mixture of MeOD and DMF and that of 2H in a mixture of MeOD with DMSO or MeOH with DMSO-d6 was measured.

Key words: SOLVENTS, BINARY SYSTEM, METHANOL, DEUTERIUM COMPOUNDS, DMF, DMSO, RELAXATION TIME, NUCLEAR MAGNETIC RESONANCE

CLC Number:
