Chlorinated Byproducts in Diisocyanates Synthesis From 35Cl Nuclear Quadrupole Resonance
Helvetica Chimica Acta, EarlyView.We combine 35Cl NQR spectroscopy & DFT to identify trace chlorinated impurities in industrial MDI streams, creating a non‐destructive “analytical ruler” for chemical process monitoring. ABSTRACT Chlorinated impurities in industrial diisocyanates production significantly impact product quality and stability, yet their speciation remains an analytical ...

Musical Chemistry and Spectroscopy: Analogies Bridging Two Worlds in Multiple Dimensions
Helvetica Chimica Acta, EarlyView.Music and spectroscopy speak the same language: that of fluctuations, line shapes, and ensembles. Herein, we establish useful analogies between music, chemistry, and spectroscopy, extending even to multidimensional and time‐resolved spectroscopies, with a mathematically‐grounded derivation and motivation.

Nuclear‐Spin Hyperpolarization of Biomolecules by Optically Enhanced NMR at Ultra‐High Field
Journal of the Chinese Chemical Society, EarlyView.This study shows that the sensitivity of liquid‐state NMR spectroscopy can be dramatically increased, with enhancement factors up to 160‐fold on a 1.1 GHz ultra‐high‐field NMR spectrometer. This advance exploits low‐concentration photochemically induced dynamic nuclear polarization (LC‐photo‐CIDNP) and it enables facile atomic‐resolution detection of ...

NTECARS: A Nonthermal Equilibrium CARS Spectra Fitting Code
Journal of Raman Spectroscopy, EarlyView.We present NTECARS, an open‐source code written in Julia for the calculation and fitting of CARS spectra under nonequilibrium conditions. Rovibrational distributions can be flexibly modeled and fitted for different use cases. The code currently implements CO2$$ \mathrm{C}{\mathrm{O}}_2 $$ and N2$$ {\mathrm{N}}_2 $$ molecules and is validated under ...

Qualitative Analysis of Biogas by Raman Spectroscopy: Effect of Pressure on Major Components
Journal of Raman Spectroscopy, EarlyView.Raman spectra of major and selected minor biogas components were studied under pressures up to 100 bar. Pressure‐induced shifts and band broadening were quantified for methane, carbon dioxide, and nitrogen, while Raman spectra of ammonia and hydrogen sulfide are presented in the context of biogas quality monitoring.
