摘要
阐述了利用核磁共振谱线宽表征液态水团簇结构平均相对大小的原理 ,通过试验确定了以 17O核磁共振谱线宽作为衡量液态水团簇结构平均相对大小的指标 ,并以温度升高过程中液态水 17O NMR谱线宽的变化对该指标进行了初步的验证 .
The principle of using NMR to measure liquid water cluster size was expatiated. Through a series of experiments the ^(17)O|NMR FWHM was selected to scale the average cluster size in liquid water. A preliminary verification was held by different water samples at different temperature.
