核磁共振波谱法 [分化] NMR spectroscopy(nuclear magnetic resonance spectroscopy)
- 用紫外光谱,红外光谱,质谱及质子—质子二维核磁共振相关波谱法提出结构1,并由单晶X衍射确证。
Its structure was assigned as 1 by UV, IR, MS and 2D-NMR spectral data, and verified by means of X-ray crystallographic analysis. - 波谱法可进行未知样品的结构鉴定,尤其是含磷化合物的核磁共振波谱特点明显,很值得利用;
The analysis of unknown products is usually conducted through spectroscopy and NMR is eminently suitable for the structure analysis of phosphonates. - 用质谱法、核磁共振波谱法、红外光谱法等,确定了未知氮杂环季铵盐型阳离子表面活性剂的结构。
Structute of nitrogen heterocyclic ring quaternary ammonium salt cationic surfactants was identi fied by mass spectrography, nuclear magnetic resonance spectra, infrared spectra and etc.
