Today I saw this enormous camphor tree at the Edison estate in Fort Myers, Florida. In his last years, Edison was obsessed with finding an economical source of latex that could be grown in the US. #NMRchat #ChemSky

Why does swapping a methyl group for a methoxy group cause such a big NMR shift?
At 125 MHz benchtop NMR, benzylic protons appear upfield, while the methoxy group resonates downfield. What’s driving this difference? Follow @qmagnetics.bsky.social for more spectra to come!🧪

According to the sweetness index, this spectrum is 180 times sweeter than a sucrose spectrum. #NMR #Chemistry #FoodScience #ChemSky #NMRchat

When it comes to benchtop NMR, higher field doesn't have to mean higher cost. At 125 MHz, the QM-125 is the highest field of any non-super-conducting magnet at less than half the cost per MHz than other benchtop instruments.🧪

If Trump and his devils are not somehow stopped, America is about to see a Nazi ethnic cleansing of 10,000 adults and children in Springfield, Ohio.

Seems like a neat NMR spectrum of WD-40 of would be a good social media post for @qmagnetics.bsky.social We did a commercial acrylic cement that turned out to be mostly DCM.

Is 50:50 PLGA truly equal lactic and glycolic acid? Copolymer analysis relies on NMR integration. With 125 MHz field strength and high dispersion, the QM-125 enables benchtop quantitative PLGA analysis, directly compared to supplier COA data.

125 MHz for protons is 2.94 Tesla.

Highest field NMR available outside of a superconducting magnet #Chemistry #Chemsky

T₁ inversion-recovery is a key first step in qNMR, defining optimal delay times to balance accuracy and speed. With 125 MHz performance and high resolution, the QM-125 is ready for qNMR—learn more in our latest application note.

Something new: COSY on the benchtop at 125 MHz! We can do it with or without deuterium, and with sample volumes down to 5 uL. As far as I know, this is the highest field COSY so far not done in a superconducting magnet. #Chemsky #NMR #Chemistry

It can do much lower concentrations. Also no-D is no problem and can do 5 uL samples.

10 mM is no problem

Concentration does not have to be that high. 10 mM is usually no problem. Sometimes a few mM is enough. We can also do very small sample volumes and it can be controlled over a LAN for automated applications.

This, from my father around 1970

At 125 MHz, benchtop NMR shows how the chiral center in (4S)-4-(propan-2-yl)-1,3-oxazolidin-2-one induces nonequivalence in nearby protons, producing diastereotopic splitting. As an Evans-type chiral auxiliary, it directs enolate geometry in asymmetric synthesis.🧪

I tried Vineeth’s PyOR NMR package by making these sims of COSY and P.COSY with SHR and TPPI processing. You can see how TPPI moves T1 noise to the edge of the spectrum and how P.COSY narrows diagonal peaks. PyOR is instructive and easy to use. Check it out! #Chemsky #NMR @vthalakottoor.bsky.social

It’s not really a FiD. That’s why it’s in quotes. I’m whacking a crystal with an rf pulse and then listening to it ring.
