Abstract :
The superposition of infrared reflectivity spectra end lattice radiation of TeO2 crystals have been investigated. Both radiation spectra at high temperatures and absorption spectra in the two-phonon range for polarizations E||c and E⊥c were performed. It is shown that in the one-phonon range it is possible to reveal two-phonon bands
