To understand how the two different motions of 1) TD1 between TD2 by the J, D-modulation and 2) TD1 between T+D by the dissociative activation cooperate for the present room temperature spin polarization in Fig. , we computed the TREPR spectra without considering T+D activation (kDISS = 0 in Fig. ) and without the anisotropic motions (k12 = 0 in Fig. ), as shown in Fig. .
