TEMPO in Solution, Melted, Solid, and Adsorbed on a Silica Surface: A Paramagnetic NMR Study

open access: yesChemistry – A European Journal, Volume 32, Issue 1, 2 January 2026.
Paramagnetic species can often be measured with EPR and NMR spectroscopy. This is demonstrated using the important radical TEMPO. All 1H and 13C NMR signals of TEMPO could be recorded and assigned. The impact of TEMPO on the chemical shifts of solvent signals and a phosphine is described.
