Numerical simulation with Easyspin of the V2 rotational pattern in 4H-SiC, considering a spin S = 3/2 with a zero field splitting D = 35 MHz and an isotropic g factor g = 2.0028; f = 9.369 GHz; the linewidth is 3G here. The nul angle corresponds to the external magnetic field aligned along the c axis of 4H-SiC. Derivative of absorption curves are shown here. The spin state populations assumed here are those of the thermal equilibrium.
