Transformations of a spin-Hamiltonian induced by reassignments of fictitious spin states
John S. Griffith · Molecular Physics · 1967
Many different spin-Hamiltonians may have the same set of matrix elements and there is, therefore, some arbitrariness in the choice of spin-Hamiltonian to represent a particular situation. This problem is discussed, with especial reference to the transformations induced by a reassignment of the correspondence between the true states and the fictitious spin states.
