NUCLEAR MAGNETIC RELAXATION IN THE PRESENCE OF PARAMAGNETIC IONS. PART II
The influence of independent processes of relaxation of paramagnetic ions on nuclear magnetic relaxation in the presence of these ions is treated. The nuclei are assumed to relax as a result of their contact with the ions through isotropic spin-exchange coupling. The second-order terms in the perturbation expansion of the relaxation tensor yield plausible contributions to the Bloch relaxation times of the nuclear spin system. The fourth-order terms yield contributions to the nuclear relaxation times that are in agreement with a phenomenological relation for this case, provided that the applied static field is not too strong and that the ionic motion can be described by a single Bloch relaxation time.
