Typically solvent peaks are the dominant feature in the NMR spectrum and often mask or seriously overlap smaller resonance from which important information of the molecule under study may be obtained. Although applied to NMR spectra, the method is general and may be applied to large peak ...
iPad Description 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 ...

A new modified singular value decomposition method, piecewise polynomial truncated SVD (PPTSVD), which was originally developed to identify discontinuity of the earth's radial density function, has been used for large solvent peak suppression and noise elimination in nuclear magnetic resonance (NMR) si...
Solvent peak suppression in high resolution NMR The solvent proton nuclear magnetic resonance peak may be suppressed to arbitrarily low levels (<10 鈭 4) by exploiting the effects of paramagnetic relaxation reagents on the solvent transverse relaxation rates. Specifically, we demonstra... RG Bryant,...

Figs. 2.19 and 2.20 suggest that the solvent compositions, which gave high swelling ratios, gave high extraction yields, and also resulted in disappearance of the endothemic peak. This means that relaxation of the aggregate structure by the dissolution of noncovalent bonds is most likely ...

CD results indicate that the change in polarity of the solvent induces an inversion of the conformation, revealed by the disappearance of the positive peak near 210 nm and then by the gradual appearance of a negative trough near 210 nm having opposite chirality. The data of NMR spectroscopy in...
