NUCLEAR MAGNETIC RELAXATION IN LIQUID AMMONIA AND CONDITIONAL INERTIAL ROTATION IN LIQUIDS

A theory of nuclear magnetic relaxation induced by inertial rotation in polar liquids is described. It is proposed that such rotation occurs only when the neighbourhood of a molecule attains an expanded lattice configuration. The non-markovian processes involved in the relaxation are expressed in terms of rate constants that occur in a formulation due to Anderson, and these are interpreted in terms of the unconditioned inertial rotation theory described in the preceding paper. The theory is used to interpret the values of T1 obtained for 14N and D in liquid ammonia. The paper concludes with an outline of a general theory of anisotropic diffusion in liquids. © 1969, Taylor & Francis Group, LLC. All rights reserved.
