[求助]关于固体31P

mengqimg · 发表于 2010-5-4 20:14:24

最近做一个31P谱，据文献该样品的核磁谱宽度从0ppm~4500ppm，我用的是Bruker 300M,请问仪器的最大谱图宽度SW却只能到1000ppm，我该怎么办？

还请高手赐教！

My understanding is that the chemical shift of your sample is in the range of 0-4500 ppm, but your signal may be not that broad. Anyway, you can run a series of P-31 MAS with different observe frequency (o1). For example, one spectrum with o1 at 200 kHz, the next one at 100 kHz, and so on. Add all the spectra, you should get the full range.

可以分段进行实验，先在-500~500试试，再改变o1p再试

有意思，找到过31P的最大化学位移是1790ppm, 可以参考Furo, I J. Phys. Condens. Matter, 2, 4217, 好像是NiP3

Bruker谱仪最大谱宽设定好像是1MHz，应该不止1000ppm的，6000ppm应该可以的吧
