Food adulteration issues have been recorded ever since people started to process foods. With the increased complexity and globalization of food supply chain, the incidence rate of food fraud has ...

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 ...

This Perspective provides an overview of recent progress, successes, challenges and future opportunities in the application of solution NMR and solid-state NMR methods to study the structure, dynamics ...

NMR spectroscopy is among the most powerful analytical techniques for the elucidation of chemical structure. It has the capability of providing detailed information about structure and dynamics of ...

A team of researchers has demonstrated that benchtop spectrometers are capable of analyzing pyrolysis bio-oils just as well as far more expensive, high-field spectrometers. A team of researchers at ...

This technique’s ability to highlight molecular structure and track reaction dynamics has garnered widespread recognition throughout academia and industry as a robust, nondestructive, noninvasive ...

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 ...

This whitepaper explores the development and implementation of such procedures using the Bruker Fourier 80 benchtop NMR spectrometer. Through examples involving model drug products, it highlights how ...

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 ...

New users of the NMR laboratory are required to engage in hands-on orientation to facility operations (e.g., laboratory access, scheduling, general use of equipment, housekeeping, etc.) and safety ...

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.
