HSQC-TOCSY solves a major problem with the proton-proton version of TOCSY, which is overlap from the many cross peaks. TOCSY cross-peaks are resolved into the 13 C dimension and …

The 3D HSQC-TOCSY experiment is specifically designed to obtain X-edited TOCSY spectra from which 1 H-1 H TOCSY correlations can be clearly assigned even in overcrowded regions …

The 1H-13C HSQC-TOCSY experiment combines 1H-13C HSQC with a 1H-TOCSY experiments to give through-bond correlations between a 13C-attached 1H to all other coupled 1H. The …

该谱图表明,对氨基苯甲酸乙酷分子中有五种不等性的氢 (没有考虑芳环上氢的区别)。 根据1H 的化学位移可初步确定：σ为1.3401~1.3758 的三重峰是甲考峰：4.0779的宽峰是氨上的两个氢， …

2006年5月1日 · <不完全去藕的技术请教: hsqc-tocsy> HSQC-TOCSY是全相关谱和检出H的异核单量子相干谱的组合脉冲实验,和不完全去藕的技术不是一回事. 请问楼主测定的是哪类化合物?

Make some assignments of your compound based on COSY, TOCSY and HSQC data. Look in particular for entry points in the spectra, some proton and/or carbon that can be assigned with …

HSQC - Heteronuclear Multiple Quantum Correlation. This 2D experiment correlates the chemical shift of proton with the chemical shift of the directly bonded carbon. On the bottom axis is a …

2005年9月1日 · We propose modifications of the sensitivity-improved gradient-enhanced 2D HSQC–TOCSY pulse scheme that yields a set of different selective spin-state cross-peak …

The selective ge-1D HSQC-TOCSY experiment allows to obtain high-quality 1D HSQC-TOCSY spectra from which 1H-1H J-correlation can be elucidated starting from a selected carbon. …

2022年10月1日 · In this paper, we present two new three-module NORD experiments, NORD {HMBC}- {HSQC-TOCSY}- {TOCSY} and NORD {HMBC}- {2BOB}- {TOCSY}, each delivering …
