Abstract :
The results of measurements performed to assess the potential of deuterated TEMPO and deuterated oxo-TEMPO for DNP are presented. These free radicals became available only recently. Polarization and relaxation processes of protons and deuterons in various deuterated alcohols and deuterated polymers have been investigated. More than 40% deuteron polarization has been obtained in samples of fully deuterated polystyrene.
