This is a simple program for calculation of diamagnetic dipolar relaxation and cross- relaxation rates between user-specified nuclear spin orders in a two-spin system. The internuclear distance is assumed to be fixed (rigid molecule). The calculation uses group theoretical properties of the dipolar interaction Hamiltonian, expanding it into a sum of irreducible tensor operators, which are rotated using Wigner matrices. The Wigner matrix elements are then autocorrelated in the Bloch-Redfield-Wangsness theory treatment.
