A search for singlet oxygen chemiluminescence at 1268 nm was made in a number of reactions of superoxide ion. Carbon tetrachloride and carbon tetrabromide reacted with suspended potassium superoxide to produce 1268-nm emission consistent with singlet oxygen. Chloroform was less reactive but produced 1268-nm emission when the concentration of superoxide ion in the halocarbon phase was increased with 1,4,7,10,13,16-hexaoxacyclooctadecane (18-crown-6). The dismutation of superoxide ion in deuterium oxide was not accompanied by 1268-nm chemiluminescence. Less than 0.02 mol of singlet oxygen was produced per mole of superoxide ion between p/sup 2/H 6 and 9.
