NUCLEAR MAGNETIC RELAXATION TIMES

Abstract

The research done deals principally with those nuclear relaxation processes in solids which depend on the presence of an electric quadrupole interaction. The results fall into two broad categories, one of which is concerned with the understanding the various relaxation processes which are encountered, and the other involves the measurement of important physical parameters. While the greatest emphasis was initially placed on the understanding of relaxation processes, probably the most important single result of this research falls into the second of these two categories. This is the measurement of an activation energy which is of importance in connection with deuteron relaxation in hydrogen bonded crystals and which turns out to be of importance also in certain theories of the ferroelectric phase transition. The significance of this connection is described in detail.
