在S= 1或更大的离子的顺磁共振谱中，某些禁戒超精细跃迁的异常强度是由于自旋哈密顿量中的交叉项引起的。这些产生于电子和核相互作用中的非对角项，并且计算的跃迁强度与对氟硅酸钒的测量密切一致。在粉末中，超精细跃迁的明显加倍被证明是由于这些项和其他项的综合效应，而这些项和其他项仅仅是由于电子分裂。
The abnormal intensity of someforbidden'hyperfine transitions in the paramagnetic resonance spectra of ions with S= 1 or more is shown to be due to cross terms in the spin Hamiltonian. These arise from off-diagonal terms in the electronic and nuclear interactions, and the computed transition intensities agree closely with measurements on vanadium fluosilicate. In a powder an apparent doubling of the hyperfine transitions is shown to be due to the combined effect of these terms and others due solely to the electronic splitting.
