The use of high magnetic field and high frequency in an unconventional spectrometer has provided very informative EPR spectra of a manganese( III ) octahedral complex for the first time. The parameters of the spin Hamiltonian operator are in fair agreement with those calculated with ligand‐field theory. High‐frequency EPR is thus a powerful tool for the structural investigation of complexes that contain metal ions with integer spins.
