Molybdophosphoric acid used as the catalyst, two alkyl glycolates were prepared. The glycolates were characterized by the boiling points and protonNMR 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。

ProtonNMR 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。

NMR spectra are often calibrated against the known solvent residual proton peak instead of added tetramethylsilane.
