摘要：

The photodissociation of the OH radical was studied at 157 nm via the detection of the product H atoms with the resonance fluorescence technique. OH radicals were produced in a fast flow cell from the reaction between H and NO2 and subsequently photodissociated by an excimer laser operating on the F2 emission. The quantum yield for photodissociation of OH was measured to be 1.10 +/- 0.28. The photodissociation cross section was calculated to be 6.6 x 10(-18) cm2 (+/- 25%) which is in good agreement with the work of Nee and Lee (Ref. 8).
