Average steady-state nuclear spin polarization (npol,av, solid symbols) and time constant (tDNP,av, open symbols) as a function of (a) hyperfine coupling (hzz,max/2π) and (b) electron-electron dipole coupling (dmax/2π). 100 biradical orientations are calculated for 1.4 s (104 × tr). Lines are drawn to guide the eye.
