The absolute quantum yield of O(¹D₂) in the photolysis of ozone in the Hartley band, between about 230 and 280 nm, has been determined using the isotopic exchange reaction between C¹⁶O₂ and ¹⁸O(¹D₂). 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(¹D₂) atoms in the 230–280-nm region within an uncertainty of only several percent.
