Temperature Dependence of the 127I-Nuclear Quadrupole Coupling in Tetramethylammonium-periodate(CH3)4NIO4

  • Dagmar G. Klobasa and Paul K. Burkert

Tetramethylammonium-periodate shows 127I-NMR second order quadrupole splitting with negative temperature coefficients α for the quadrupole coupling constants and a second order phase transition. From these measurements one can exclude the ratio (rcation/ranion) > 1 to be the origin of the anomalous temperature dependence in NH4IO4.
