## Abstract Spinโlattice relaxation mechanisms of nuclear spins in solids in the presence of low concentrations of paramagnetic centers are discussed. Apart from the electron spinโlattice relaxation mechanism, threeโspin processes involving two electron spins and a nuclear spin may also play a role
## Abstract Dynamic nuclear polarization of nuclear spins via the solidโstate and thermal mixing effects is discussed. Continuousโwave Sโ and Xโband microwave radiation have been employed to measure ^13^C signal enhancements and polarization times for ^13^C nuclei in a natural type Ib diamond as a
