Two weak absorption lines are observed in the submillimeter region of the spectrum of the antiferromagnetic crystal CuCl2-2H20. Their frequency dependence and the polarization and intensities as a function of the magnetic field are investigated. The lines are uniquely identified as exchange modes of the antiferromagnetic resonance (AFMR).
