Optical characterization of the oxygen dimer in silicon has been performed for first time. The vibrational IR absorption bands at 1012, 1060, and $1105{\mathrm{cm}}^{\ensuremath{-}1}$ are shown to arise from this complex. Using heat-treatment studies, binding energy is determined be about 0.3 eV. Indications high migration ability predicted earlier found as well.
