Nuclear magnetic resonance (NMR) spectroscopy is integral to metabolic studies; yet, it can suffer from the long acquisition times required to collect data of sufficient signal strength and resolution. The use of non-uniform sampling (NUS) allows faster collection of NMR spectra without loss of ...

A quantitative method to record 1H-13C correlation NMR spectra (Q-HSQC) is presented. The suppression of 1JCH-dependence is achieved by modulating the polarization transfer delays of HSQC. In addition, the effect of homonuclear couplings, as well as relaxation during the pulse sequence are discu...
Data processing is a critical step in the analysis of NMR spectra, especially in 2D NMR spectroscopy. It is important because the spectra obtained from NMR contain noise and artifacts that can interfere with the interpretation of experimental results. Effective data processing can remove noise and ...

2D NMR techniques such asH-C heteronuclear single quantum correlation (HSQC) was used for the compositional and configurational assignments ofH andC{H} NMR spectra for various resonating signals. 2DH homonuclear double quantum filter-correlated spectroscopy (DQF-COSY) is used to get better insight ...
