(a) The experimental (black) and simulated (red) ESR powder spectra at 435.2 GHz. The simulation was performed employing eq. 1 and the parameters given in the main text. (b) The energy level diagram with the external applied field being parallel to the x-axis (red thick lines) and the y-axis (thin blue lines). The vertical arrows correspond to ESR transitions observed at 435.2 GHz. (c) Simulations for frequency vs. field plot showing the ground ESR transition positions, at 3.5 K, with the field applied parallel to the x (red), y (blue) or z (green) axis. The points are the measured α, β and γ transitions while the solid lines are the simulation. The thick and dashed lines correspond to half-field transitions and normal ground state ESR transitions, respectively.
