磁共振方法研究12-钨磷酸水合物中水分子的运动状态

MAGNETIC RESONANCE METHOD STUDIES ONTHE MOVING STATE OF WATER MOLECULES IN12-TUNGSTO PHOSPHORIC ACID HYDRATE

本文使用以Cu(Ⅱ)为顺磁探针的ESR以及宽谱线~1H-NMR等磁共振方法,研究了12-钨磷酸水合物中水分子的运动状态,结果表明水合水的活动性不仅取决于温度,而且还与12-钨磷酸水合物中的含水量有关。

The moving states of water molecules in the 12-tungsto phosphoric acid hydrate have been investigated by ESR with Cu(II) as a paramagnetic probe and 1H-NMR of wide spectra. The results show that mobility of hydrated water molecules is not only dependent on the temperature, but also related to the amount of water molecules which exist in 12-tungsto phosphoric acid hydrate.
