采用多种核磁共振技术测定了一种重要有机膦酸２－磷酸基丁烷－１，２，４三核酸（ＰＢＴＣ）的分子结构，发现其分子中至少存在着２对不等价同碳质子；测取了分子中各磁性核之间的偶合常数，并依靠这些数据解释了有关谱峰的形状特点；归属了ＰＢＴＣ工业产品中的杂质峰，并解释了ＰＢＴＣ各谱峰随浓度改变而发生位移的原因。
A variety of NMR techniques were used to determine the molecular structure of PBTC, an important organic phosphonic acid butane-1,2,4-tric acid (PBTC). It was found that there are at least two pairs of unequal equivalents of carbon proton ; Measured the coupling constants between the magnetic nuclei in the molecule and relied on these data to explain the shape characteristics of the peaks; assigned the impurity peaks in the PBTC industrial product and explained that the PBTC peaks peaked at varying concentrations The reason for the displacement.
