Alkali metal atoms were codeposited with oxygen at high dilution in argon on a sapphire window cooled to 17K. Ultraviolet spectra contained a medium intensity absorption near 250 nm which exhibited a long wavelength component between 269 and 275 nm for the heavier alkali metals. The 250 nm band arises from M/sup +/O/sub 2//sup -/ and is assigned to a ..pi.. ..-->.. ..pi..* superoxide transition, and the absorption near 270 nm, which increased on sample warming, is attributed to M/sup +/O/sub 4//sup -/.
