DYNAMICS OF PROTON-TRANSFER IN SOLUTION BY NMR RELAXATION

The expression has been derived for the rate of intramolecular part of the relaxation induced by the motion of nuclei transferred between the two sites of unequal energy and by isotropic reorientation of nuclear pairs. This expression should be useful in analyzing T//1 data for hydrogen bonded liquids. The relaxation time T//1 of protons in H//2 O-D//2O mixtures has been measured and analyzed on the basis of the presented theory.
