dc.description.abstractBy varying the pulsewidth of the output from two dye lasers, we have verified experimentally that the steady‐state interference level of OH due to laser‐induced dissociation of ozone decreases linearly with decreasing pulsewidth of the exciting radiation. At low pressures, further reduction in the interference level due to the transient nature of OH formation processes was also observed. These results should greatly facilitate measurements of OH concentrations in the atmosphere.en_US

dc.identifier.citedreferenceStrictly speaking, Eq. (A.1) is valid for the case of square‐topped exciting pulses only. The validity of Eq. (1) for the steady state is more general and is independent of the pulse shape. This is because Eq. (1) also results directly from the differential equations for the rate analysis without proceeding through Eq. (A.1). It follows that no correction is necessary to account for the difference, if any, in pulse shape between the four different sources used in Fig. 1 for excitation. The same cannot be said about the Δt3Δt3 dependence, however.en_US
