We’re proud to support local research efforts at the CSU Powerhouse Energy Campus, where the QM-125 NMR now provides everyday NMR accessibility to a research group. They will soon be using it for tracking electrochemical reactions, advancing their research within their own lab. #NMRchat #benchtopNMR

Check out the ¹⁹F NMR spectrum of NaBF₄ at 3 T. Coupling of ¹⁹F to ¹¹B gives a quartet, while ¹⁰B yields a septet. The ¹¹B quartet dominates due to its higher natural abundance. The difference in multiplicity creates a beautiful example of ¹⁹F – ¹⁰/¹¹B coupling! #NMRchat #Chemistry #FluorineNMR

The QM-125 delivers high-performance flow-based sampling built for automation and next-gen NMR.

Back in 1964, Patterson and Wells [J. Mol. Spect. 14, 101-111] showed that this occurs because the difference between the H-F ortho and meta J couplings is small compared to their sum.

125 MHz 1,4-difluorobenzene proton and fluorine multiplets appear first-order with equal J-couplings, even though the protons are not magnetically equivalent. Observed splitting of 6.08 Hz in both multiplets is close to the average of these couplings.🧪 #NMRchat #chemistry #benchtopnmr

Stacked spectra of vanillin in benzene-d₆ and CDCl₃ reveal how solvent choice shapes chemical shifts. Benzene-d₆, with its strong anisotropic ring current, subtly shields aromatic protons and can spread the aromatic region compared to CDCl₃.

Acetaminophen, also known as paracetamol, is a widely used analgesic and antipyretic that relieves pain and reduces fever. It is cited as one of the safest and most effective ways to treat pain and fever.🧪 #NMRchat #Chemistry #flowchemistry #benchtopnmr #tylenol #acetaminophen

At 125 MHz, benchtop NMR highlights methyl salicylate. Best known as wintergreen scent, it's used in flavorings, fragrances, and topical pain-relief products. Wintergreen plants produce methyl salicylate as a defense from pathogens and predators.🧪 #NMRchat #Chemistry #flowchemistry #benchtopnmr

At 125 MHz, benchtop NMR highlights the aromatic, methoxy, and aldehyde signals of vanillin. Widely recognized as the main component of vanilla-bean flavoring, it is also used in fragrances, cosmetics, and to improve the flavor of medications.
