The presence of vibrationally excited oxygen in the active medium of a chemical oxygen - iodine laser is discovered using the emission technique. Using the analysis of the luminescence spectra of oxygen molecules on O{sub 2}(b{sup 1{Sigma}}{sub g}{sup +}, v=i){yields}O{sub 2}(X{sup 3{Sigma}}{sub g}{sup -}, v'=i) (i=0, 1, 2) electronic vibrational - rotational transitions, it is shown that {approx}22 % of O{sub 2}(b{sup 1{Sigma}}{sub g}{sup +}) molecules are at the first vibrational level and {approx}10 % are at the second one. Moreover, due to the fast EE energy exchange, a mean number of vibrational quanta per one molecule in each of the O{sub 2}(X{sup 3{Sigma}}{sub g}{sup -}), O{sub 2}(a{sup 1{Delta}}{sub g}) and O{sub 2}(b{sup 1{Sigma}}{sub g}{sup +}) components is approximately the same and amounts to 30 % - 40 %.
