Crosshyphen;relaxation determination of short quadrupolar spinndash;lattice relaxation rates in solids: Strong mixing in KH2AsO4and Ag2H3IO6

摘要

The application of dipolar proton (I) spinndash;lattice relaxation time measurements for the determination of fast quadrupolar spinndash;lattice relaxation rates on nonresonantSspins, the signals of which are too weak to be measured directly, are discussed in the limit of strongIndash;Sdipolar coupling. The spinndash;lattice relaxation of the common1Hndash;75As dipolar reservoir in KH2AsO4and the common1Hndash;127I dipolar reservoir in Ag2H3IO6are used to illustrate the above technique.
