AB The possibility is considered of carrying out submillimeter-wave spectral investigations of semiconductors by means of a high resolution spectrometer with backward-wave tubes. Results of a  study of the excitation spectra of small impurities, D-(A +) centers and free excitons in germanium are presented.
