Contribution of scalar coupling pathway in the relaxation of germane and tetrahalogermanes
73Ge relaxation in GeH4, GeCl4, and GeBr4, and 1H relaxation in GeH4 have been studied, and found to contain a scalar coupling mechanism in a spin-spin relaxation. Furthermore, a scalar spin coupling constant, J(73Ge–35Cl) = 24Hz, was obtained.
