Description
Summary:Nuclear electric quadrupolar relaxation of deuterium or quadrupolar metal nuclei, due to diffusing hydrogen or deuterium, is estimated to dominate magnetic dipolar relaxation in metal-hydrogen systems. The longitudinal magnetization recoveries for quadrupolar relaxation can be linear combinations of several exponentials and expressions for the exponents depend on the spin I, whether a spin-temperature exists in the system and whether a static quadrupole interaction exists. Some limiting cases and examples are discussed.
