NMR Solvent Peaks is a conveniently-searchable version of the ungainly table of NMR data most organic chemists keep a copy of nearby. Instead of searching through the table for a peak near your unidentified peak, just enter your solvent and the peak's multiplicity and location and you'll have...

The intensities of the 1H-peaks properly indicate the proportion of these protons within a molecule, and therefore they are extremely useful to estimate the atoms and the percentage of each enantiomeric form (percentages in Figure 1). Actually, just after mass spectrometry (MS) techniques, ...
Figure 7: Solvent mixture analysis of a Tequila sample.Alcohol and water is a common solvent mixture. It contains one well resolved peak at about 1.2 ppm and two overlapping peaks between 2.7 and 6.0 ppm. The peak at 1 ppm is from the methyl protons (red box) of the ethanol and the ...

(B) Full 1H spectrum recorded at 298 K, shows the various regions (NH, phenyls, N–CH3 and Hβ) as well as solvent signals (EtOH and H2O) and internal reference TSP; inset highlights the two peaks for the N–CH3 group corresponding to the two conformers. (C, D and E) 2D HSQC ...

The higher the intensity of the peaks in its pseudo-1D spectrum, the greater the contribution of the peak in each PC, thus enabling us to point out the main metabolites in the aqueous extract that contributed to the separation of the four cell lines in both PC1 and PC2. An analysis of...
