The absolute quantum yield of O( 1 D 2 ) in the photolysis of ozone in the Hartley band, between about 230 and 280 nm, has been determined using the isotopic exchange reaction between C 16 O 2 and 18 O( 1 D 2 ). A value of 1.00 ± 0.05 has been obtained within a 95% confidence limit. A value of unity may therefore be accepted as the average quantum yield of O( 1 D 2 ) atoms in the 230–280‐nm region within an uncertainty of only several percent.
