【求助】请高人帮忙解析下固体核磁碳谱，

实验条件如下：The corresponding 13C resonance frequencies were 100.6 MHz. Samples were packed in a 7 mm ZrO2 rotor and spun at the magic angle (54.7o), and the spin rate was 7 kHz. 1H-13C CP/MAS NMR spectra were recorded with a contact time of 1.2 ms and a recycle delay of 2 s. The 13C chemical shift was externally referenced to the high field resonance of hexamethylbenzene at 17.17 ppm as a secondary reference.

没什么变化。就是下图多了些杂质出来。

这样的课题直接就检测固体核磁, 有些草率.
不如萃取浓缩, 视需要某种纯化, 检测液体核磁.

赞同林老师的建议，这样解谱太难了
