NMR spectra are typically collected in solutions made up of deuterated solvents due to the fact that a protonated solvent will yield large solvent peaks which may hide the solute’s spectral features.

NMR spectroscopy is a physicochemical analysis technique that is based on the interaction of an externally applied radiofrequency radiation with atomic nuclei. During this interaction there is a net ...

Please prepare your samples in the designated area or under a hood, and not on top of the magnet. The chemical shifts (d) of solvent signals observed for 1 H NMR and 13 C NMR spectra are listed in the ...

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 ...

An initial step of most NMR studies is identifying peaks in the obtained spectrum. Producing a peak list is especially crucial if the spectrum is automatically prepared. Peak picking is still ...

Lidocaine is a widely used local anesthetic and anti-arrhythmic drug with an immediate onset of action. Lidocaine is used topically to alleviate the burning, itching, and pain caused by skin ...

A recently developed Metabolomics informatics solution from raw data processing to metabolite database searching, compatible with multiple instruments, has been successfully applied to the analysis of ...

For the majority of users conducting nuclear magnetic resonance (NMR) spectroscopy today, sample preparation follows a similar path: isolate a compound or compounds from a reaction mixture (or if ...
