Paramagnetic relaxation enhancement is a fundamental molecular physical phenomenon, manifested as an acceleration of the relaxation times of a slowly relaxing spin Sslow due to the magnetic interaction, dipolar or exchange, with a fast relaxing spin Sfast. Here, we examine the general case of the enhancement of T1slow due to a fast relaxer Sfast with rhombic g-tensor. By using the formalism of Kubo and Tomita we derive an analytical expression for the dipolar effect on T1slow.
