Benchmark simulations of 2H Mims ENDOR spectra for D2 and D5 of Im1, assuming glf to correspond to the g-frame axis Zg (//Zm). The orientation of the Im1 plane with respect to the g-frame was characterized by azimuthal angles ϕh = 0 (solid traces), 45° (long-dashed traces), and 90° (short-dashed traces). Simulation parameters: aiso = 0 MHz; T⊥ = −0.35 MHz; e2Qq/h = 0 MHz; mw frequency, 29.966 GHz; τ= 360 ns; Bo = 864.8, 897.8, 928.8, 999.8, 1070.3, and 1141.8 mT for traces 1 through 6, respectively.
