The spectrum of O 2 − ion was measured in several media. The absorption spectra of O 2 − in KCl discs, in acetonitrile and the reflection spectrum of KO 2 showed the maximum absorption in the range of 240 mμ. Solutions of KO 2 in liquid ammonia and ethylene diamine are characterized by an absorption band in the range of 370–380 mμ. It is shown that the latter absorption was misinterpreted and is due to the nitrite ion which is formed as a by‐product, rather than to the O 2 − ion.
