Structural features have been observed in the absorption spectra of single crystals of the antiferromagnetic semiconductor CuO in the interval 0.08-1.50 eV. The nature of these features is discussed in connection with the known spectra of high-temperature superconductors based on CuO and the spectra of 3d-antiferromagnetic insulators.
