Multiple‐quantum transitions in the electron paramagnetic resonance spectrum of naturally doped (≈ 10 ppm) CaS: Mn II powder are reported. Considerable resolution enhancement is achieved because of the lack of strain broadening of the EPR lines, due to the very good crystallinity of the powder. Multiple‐quantum transitions are identified by their linewidth, their saturation behavior, and their magnetic field position. Two‐, three‐, and five‐quantum transitions were identified, but not the four‐quantum transitions. A line at g = 1.983 is assigned to Cr III impurities at low concentration, which also exhibits a two‐quantum transition at high microwave power.
