Abstract

The unitary group approach to angular momentum theory is applied to evaluate matrix elements of the nuclear spin-spin coupling Hamiltonian. The important case of two spin $-{1\over 2}$ particles in an external field which is a prototypical case for many NMR studies is analyzed in the framework of the unitary group approach. To aid in the evaluation of matrix elements of the nuclear spin-spin coupling Hamiltonian for higher spin nuclei, we introduce simple factorization schemes for evaluating two body operator matrix elements in the Unitary Group Approach. The results are applied to an $A\sb4 B\sb3$ system and compared with previous results in the literature. A method of relating matrix elements of two-body operators for larger systems to smaller systems is discussed. Some of the techniques for the simplification of two-body operator matrix elements may be useful in other physical applications of the unitary group approach.Dept. of Physics.
