A) Paramagnetic relaxation contributions from rotationally correlated coupling between a protein-bound nitroxide and a protein-bound water molecule as a function of the proton Larmor frequency. Rotational correlation times are 20, 50, and 100 ns increasing from bottom to top, the protein concentration is set at 1.0 mM, and the inter-moment distance is set to 8 Angstroms. B) Paramagnetic relaxation contributions from rotationally correlated coupling between a protein-bound nitroxide and a protein-bound water molecule at a proton Larmor frequency of 100 kHz as a function of inter-moment distance assuming that the rotational correlation time is 50 ns and the water molecule exchange is 106 s-1.
