核磁共振谱法
nuclear magnetic resonance spectrometry
- 本文用衍生物合成、降解反应、红外光谱、核磁共振谱及x -射线衍射晶体分析法研究了它的化学结构。
Its structure has been studied through a series of chemical synthesis, preparation of derivatives, degradations and IR analyses, and ultimately determined by X-ray diffraction. - 简述核磁共振氢谱（ PMR）定量测法，并列举了一些应用实例。
This paper simply relates the quantitative analysis by PMR spectroscopy and enumerates some applied samples. - 方法采用RP HPLC法对荧光素钠注射液进行成分分析并用硅胶柱色谱法对主要杂质进行分离，根据质谱和核磁共振谱数据进行结构鉴定。
Methods The components were analyzed using RP-HPLC. The main impurities were separated using silica gel column chromatography, which were identified by MS and NMR.
