Anisotropic EPR spectra (X-band, 9.5 GHz) ?

?
This is an EPR spectrum of an electron in an isotropic environment with g = 2.003.
This is an EPR spectrum of an electron in an environment with axial symmetry, gx = 2.050 and gy = gz = 1.950.
This is an EPR spectrum of an electron in asymmetric environment with gx = 2.050, gy = 2.003 and gz = 1.950.
This orange line is an axial EPR spectrum.
