Dynamic nuclear polarization in the liquid state via Overhauser effect is enabled by the fluctuations of the electron-nuclear hyperfine interaction. Fermi contact (or scalar) hyperfine coupling can be modulated by molecular collisions on timescales o

Tracking a time-varying indefinite number of objects in a video sequence over time remains a challenge despite recent advances in the field. Most existing approaches are not able to properly handle multi-object tracking challenges such as occlusion,

$$^1$$ 1 H ENDOR spectra of tyrosyl radicals (Y$$^\bullet$$ ∙ ) have been the subject of numerous EPR spectroscopic studies due to their importance in biology. Nevertheless, assignment of all internal $$^1$$ 1 H hyperfine couplings has been challen

Publikováno v: Physical Chemistry Chemical Physics

We report a large variation in liquid DNP performance of up to a factor of about five in coupling factor among organic radicals commonly used as polarizing agents. A comparative study of 1H and 13C DNP in model systems shows the impact of the spin de
