DIRECT AND INDIRECT DIPOLE-DIPOLE COUPLING BETWEEN CD-111, CD-113 AND TE-125 IN SOLID CDTE

In nuclear magnetic resonance spectra of113Cd and125Te in solid CdTe a splitting has been found. The intensity of the satellites is proportional to the natural abundance of111Cd,113Cd and125Te. From a NMR rotation pattern of125Te in a CdTe single crystal in addition to a direct dipole-dipole coupling between125Te and111Cd,113Cd an indirect anisotropic dipole-dipole interaction has been observed. If the direct dipoledipole coupling is calculated from crystal geometry and from the gyromagnetic ratios of113Cd and125Te, the indirect dipole-dipole interaction is J⊥(113Cd-125Te)=(765±90)Hz perpendicular and J∥(113Cd-125Te)=(435±120)Hz parallel to the internuclear axis. © 1979 Springer-Verlag.
