Quantitative measurement of the relative number of rare spins of individual lines in solid state cross polarization NMR has been hampered by the spin-latlice relaxation in the rotating frame and the finite and different cross polarization transfer rates. In this article a simple method which combine

## Abstract Spin‐lattice relaxation mechanisms of nuclear spins in solids in the presence of low concentrations of paramagnetic centers are discussed. Apart from the electron spin‐lattice relaxation mechanism, three‐spin processes involving two electron spins and a nuclear spin may also play a role
