Fig. 3: An example of the relationship of the molecular symmetry and the direction of SOC.

By the ISC transition between S1 and T3 states of the equatorial isomer, the in-plane components, X and Y, of the SOC are canceled and only the out-of-plane components, Z, remains. Source data are provided as a Source Data file.
