Typical ranges in chemical shifts are in the ppm range (parts per million) and are about 15 ppm for 1 H, 250 ppm for 13 C, 400 ppm for 15 N, and 35 ppm for 31 P. Usually the NMR spectrum shows more ...

In order to improve the efficiency of NMR-based metabolomics studies, we have developed KnowItAll® Informatics System, Metabolomics Edition as a consistent and integrated software environment that ...

Unfortunately, many 1H-NMR spectra are severely overlapped due to the multiplet structure caused by homo-nuclear scalar couplings. "Pure shift" NMR spectra, also known as broadband homonuclear ...

Figure 1 shows the 1H and 13C NMR spectra, which are a 50% solution of methyl linoleate solution dissolved in CDCl3. Both these spectra were achieved and processed in under 2 minutes.

1 H NMR Sensitivity. NMR spectroscopy may theoretically appear less sensitive than other frequently employed analytic ...

Two-dimensional (2D) 1H-13C methyl correlated NMR is increasingly being recognized as a powerful tool to characterize the higher order structure (HOS) of monoclonal antibody (mAb) therapeutics. 2D ...

The accumulation of plastic waste worldwide poses a serious threat to wildlife and ecosystems. Catalytic processes that ...
