| 摘 要： | 使用400MHz核磁共振仪测定了羟基乙叉二膦酸(HEDP)和甲胺二甲叉膦酸(MADMP)的^1H、^13C和^31P谱．研究了P对H和C的偶合裂分，探讨了N对^1H、^13C和^31P谱的影响．发现P对邻近C、H的偶合作用很强，而N的存在使谱图变得复杂．结果表明核磁共振波谱适合于有机膦酸的结构鉴定，是剖析该类化合物的一种较好方法。

| Abstract: | ()~(1)H, ()~(13)C and ()~(31)P NMR of hydroxyethylidenediphosphonic acid(HEDP) and methylaminodimethylenephosphonic acid (MADMP) were measured by using 400 MHz NMR spectrometer. The coupling split of P to H and C was investigated and the effects of N on ()~(1)H, ()~(13)C, ()~(31)P were also discussed. The coupling effects of P on C, H nearby are strong, and N makes spectrum diagram complicated. It is shown that NMR is an appropriate approach to the analysis of phosphonic acids. |
