Macroscopic equations for nuclear spin resonance in density matrix formalism Jog, Shridhar Dattatraya

Abstract

Methods of setting up generalized Bloch equations governing the time dependence of macroscopic magnetization for a system of nuclei of spin I, in given magnetic and electric fields, have been proposed for the degenerate case by Bloom, Hahn and Herzog and by Lureçat, and for the non-degenerate case by Bloom, Robinson and Volkoff. In this thesis an attempt is made to give a unified discussion of these methods by utilizing the density matrix formalism and to demonstrate the interrelationship between them. Relaxation effects are not considered. The general theory is developed in terms of the density matrix formalism and is applied to the non-degenerate and the degenerate cases. The results are discussed and compared with those of the previous investigators.
