Take 30 minutes to understand photoinduced hyperpolarization NMR! After photosensitizer excitation, a radical pair is formed. In a magnetic field, this radical pair undergoes the radical pair mechanism, and eventually, radical recombination yields hyperpolarization.

I explained photo-CIDNP hyperpolarization for beginners. Learn all you need to know and get started with the most agile NMR hyperpolarization technique.

Please review this recently published paper authored by Oliver Kappe and his colleagues in Graz. In their study, they utilized an advanced high-pressure, high-temperature reactor to quickly modify reaction parameters for a Michael addition. Within this experimental setup, they evaluated the reaction's conversion using FTIR and a Spinsolve benchtop NMR spectrometer. The ability to simultaneously control five distinct variables—residence time, temperature, catalyst loading, reaction concentration, and reagent loading—enabled rapid data acquisition and the successful development of a temperature-dependent kinetic model for this reaction. https://lnkd.in/eMPbBQiy #NMR #benchtopNMR #magritek #spectroscopy

Nice work Peter Sagmeister, C. Schiller, P. Weiss, K. Silber, S. Knoll, M. Horn, C. A. Hone, J. Williams and C. Oliver Kappe. Not the first in this topic and I am sure, not the last one! Continue in this direction! #ReactionChemistry #Engineering #ProcessScaleUp #FlowChemistry #ChemicalEngineering

Congratulations to the Krylov group, and one of Q-Chem's own staff scientists, on their recent publication in the Journal of Computational Chemistry, in which they simulate the 2PA spectrum of the solvated SCN- radical using Q-Chem's EOM-CCSD, QM/MM, and 2PA spectra features. Their work highlights the role of native symmetry in the no-symmetry environment. Also check out the cover image for this manuscript, which is featured as the front cover of the May issue!

Detect natural abundance 13C and 15N on a benchtop NMR spectrometer! Scientists from Johannes Gutenberg University Mainz developed a novel approach to hyperpolarizing small molecules directly in situ: a benchtop NMR spectrometer that can reach up to 12% polarization! This could accelerate the recording of 2D heteronuclear experiments on benchtop NMR spectrometers as the hydrogen bubbles through the sample disposed in the spectrometer, which is ready to be measured. The polarization transfer is performed using spin-lock-induced crossing. It is quite cool because it is simple but still requires finding the matching condition for each molecule (Figure 2 of the manuscript). On the other hand, this could be leveraged to achieve some additional resolution on the benchtop. Polarization can be recycled several times with the same sample, and hyperpolarization is achieved within 10 seconds! Link to the article: https://lnkd.in/eDtJSnfD One more win for benchtop NMR. Will it be enough to deter superconducting magnets? Look at my previous post on the topic for more insight: https://lnkd.in/eGqwjgXm #innovation #chemistry #nmr

Great to see what can be done with benchtop on hetetonuclei once hyperpolarization is utilised. Methods avoiding superconducting magnets are surely only going to become more important with helium supply issues in the future and cryofree polarizers are a lot easier than cryofree high field magnets

USA Magnetic Resonance Facility presents Magnetic Resonance Fun Facts. Fact #2 Did you know? Using a cryoprobe NMR spectrometer, the typical acquisition time for 1D- and 2D- NMR experiments for a 1 mg sample of a 463-Da compound will only take 10 hours. With this technology, more samples can be analyzed, and more organic compounds will be identified in return!
