Abstract

The ambiguity problems of the spin Hamiltonian are discussed. The matrices in the spin Hamiltonian are found to be undetermined by a multiplicative Euler matrix if only measurements in solid phase are considered. The application of circularly polarized radiation or the detection of resonance at zero magnetic field cannot resolve the ambiguities in the spin Hamiltonian, ENDOR measurements partly resolve them, while relaxation measurements in liquid completely resolve them. The fact that supplementary information can be obtained from liquid phase measurements is explained by the transformational property of the time-dependent Schrödinger equation under rotations of the spinor fields. The consequences of the combination of data arising from different phases are analyzed. Second- and third-order relaxation formulas are derived in the case of isotropic random rotation.
