Enhanced Resolution in EPR Spectroscopy Using para-Hydrogen Matrices. [PDF]
Angew Chem Int Ed EnglWe demonstrate the advantageous properties of solid para‐hydrogen (p‐H2) matrices for electron paramagnetic resonance (EPR) spectroscopy by investigating the 2,2,6,6‐tetramethylpiperidinyloxyl (TEMPO) radical and an in situ generated P‐centered mono‐radical.

Gas-phase Ortho-to-para Ratio of Formaldehyde Formed at Low Temperatures in Laboratory Ices
The Astrophysical Journal Letters, 2023 The ortho-to-para ratio (OPR) of formaldehyde (H _2 CO) has been used as a probe to estimate the formation temperature of molecules in interstellar, circumstellar, and cometary environments, relying on the assumption that nuclear spin conversion is ...
