38. The program used here is the program described in ref. 12. The Hamiltonian matrix was diagonalized numerically to obtain the energies of the spin states, which, on substitution into the van Vleck formula, gave the theoretical values for the magnetic susceptibility. A least-squares program then compared calculated and observed susceptibility curves and changed the parameters to get the best fit
