核磁共振波谱的解析观察图谱1.检查图谱灵敏度是否足够(若要进一步提高灵敏度,可增加浓度或增加累加次数);谱宽范围是否足够;图谱分辨率是否良好;要注意大分子谱线的分辨率低,以及顺磁性物质(如Fe~(3+)、Cu~(2+)、Mn~(2+)和O_2等)所引起的分辨率降低。2.判断图谱中有否折叠峰。这在福里哀变换仪 Analytical Spectra of Nuclear Magnetic Resonance Spectroscopy 1. Check whether the sensitivity of the spectrum is adequate (to increase the sensitivity further, increase the concentration or increase the number of additions); whether the spectral width is adequate; whether the spectral resolution is good; pay attention to the resolution of the macromolecular spectral line Low resolution, and resolution reduction caused by paramagnetic substances such as Fe 3+, Cu 2+, Mn 2+ and O 2. 2. Determine whether there are peaks in the map. This is Mori Mori transform instrument
