proton nmr

英汉例句

Molybdophosphoric acid used as the catalyst, two alkyl glycolates were prepared. The glycolates were characterized by the boiling points and proton NMR spectra.
以钼磷酸为催化剂合成了两种羟基乙酸酯，并经沸点和核磁共振氢谱确定了它们的组成和结构。
The resulted D, L-lactide and glycolide were found to have ring structure by fourier transform infrared spectrometry and proton nuclear magnetic resonance(1H NMR) spectrometry.
通过傅立叶红外光谱和氢核磁谱（1H NMR）测试表明所合成的丙交酯和乙交酯具有环状结构。
Proton NMR two dimensional time-domain data are collected based on the inversion-recovery technique. Double Fourier transformation of those data yields the two dimensional frequency-domain data.
基于反转恢复法建立质子NMR二维时域数据，经双重付里叶变换获得二维频域数据。
