Abstract
The invention relates to compounds of general formula (I) wherein X is C═O or SO2, M is NR2 or O, and Q1 and Q2 are nitroxide-containing radicals, and their use as a Dynamic Nuclear Polarization (DNP) agent for polarizing an NMR-active spin of a nucleus of an analyte in Nuclear Magnetic Resonance (NMR) spectroscopy.
