Abstract
A new spectrum in the region 3115–2680 Å has been obtained in absorption by a flash discharge technique, and is attributed to the PO2 radical. Vibronic and K structure analyses are performed which show conclusively that the new spectrum is analogous to the 2490 Å system of NO2, and thus represents the [Formula: see text] transition of the PO2 radical. The vibronic assignments are confirmed by an isotopic study of the spectrum using oxygen-18. The various frequencies obtained are: [Formula: see text], [Formula: see text], and [Formula: see text]. A predissociation is observed from which an upper limit to the energy of dissociation into P + O2 is set at 35 500 ± 100 cm−1.
