Abstract
For pt.I see abstr. A79623 of 1974. The theory of nuclear spin relaxation due to dipole-dipole interactions between diffusive species on a crystal lattice has been formulated exactly and applied to a FCC lattice in a previous publication. The results are presented here for BCC and SC lattices and it is found that the differences between the exact theory and the approximate Torrey theory are larger in these lattices than in the FCC lattice.
