  Nuclear quadrupole coupling in ND₄ReO₄and ND₄IO₄

  摘要：

  The temperature and pressure dependences of the 187Re nuclear quadrupole resonance frequency in ND4ReO4 are reported, and compared with corresponding data for NH4ReO4. The temperature dependence of the deuteration shift is similar to that of the pressure coefficient of the quadrupole frequency, (∂ν/∂P)T. In both ND4ReO4 and NH4ReO4, there is a rapid change in the slope of the graph of (∂ν/∂P)T vs temperature, rather than the discontinuous change reported previously; there is no significant shift in the temperature of this feature upon deuteration. It is concluded that changes in the ammonium ion rotational motion near 200 K are the result, and not the cause, of other structural changes in the crystal. The quadrupole frequency in ND4 127IO4 has been measured at room temperature.

  Abstract The heat capacity of the scheelite salt: deuterated ammonium metaperiodate, ND4IO4, was measured from 8 to 329 K using adiabatic calorimetry. The heat capacity against temperature curve shows a broad maximum with a peak around 200 K which is typical of other ammonium scheelites. A small peak in the curve around 275 K resulted from fusion of a saturated D2O salt solution trapped in the lattice

  摘要 白钨盐：氘化偏高碘酸铵 ND4IO4 的热容量使用绝热量热法从 8 到 329 K 测量。热容对温度曲线显示出一个宽广的最大值，峰值在 200 K 附近，这是其他铵白钨矿的典型特征。曲线中 275 K 附近的一个小峰是由晶格中捕获的饱和 D2O 盐溶液的融合引起的。ND4 的标准摩尔热力学量值高达 330 K。
