We study infrared-active vibrations of interstitial oxygen in Czochralski-grown samples of Si_{x}Ge_{1-x} alloys with the silicon content from 0 to 1 between room and liquid nitrogen temperature. The measurements were performed on a large series of samples including single crystals of Si and Si-rich alloys, and polycrystalline samples of alloys with a higher Ge content. We focus on quantitative data on the compositional and temperature evolution of the strongest absorption band above 1100 cm^{-1}, related to the asymmetric stretching of the Si_{2}O pseudomolecule. We have also observed a pronounced Fano-like resonance centered at 520 cm^{-1}.
