求助:固体核磁氢谱分析?之前一直没有接触过核磁共振,求高手教导怎么分析,样品是利 蛇纹石 ,下面是做核磁的地方给我发过来的参数什么的,我拍漏了什么直接复制了:The1H MAS spectra were recorded on a Bruker AVANCE III 400 WB spectrometer equipped with a 4 mm standard bore CP MAS probehead whose channel was tuned to 400.18 MHz, using a magnetic field of 9.39T at 297 K. The dried and finely powdered samples were packed in the ZrO2 rotor closed with Kel-F cap which were spun at 12 kHz rate. The experiments were conducted at a contact time of 2 ms. A total of 16 scans were recorded with 5 s recycle delay for each sample. All 1H MAS chemical shifts are referenced to the resonances of adamantane (C10H16) standard (d=1.91).1.png2.png3.png查看更多4个回答 . 11人已关注
