摘要:
For samples whose NMR spectra are dominated by the broad signals of macromolecules or functionalized nanoparticles, transverse relaxation (T-2) spectral editing tends itself to a precise identification and determination of small molecules such as metabolites or contaminants. In order to retain the most sensitivity, we propose a method for efficiently removing the interference of spin-spin couplings that typically lead to signal losses in standard pulse schemes designed for T-2. editing.
