The electronic Raman transition hetween 2 P 3/2 and 2 P 1/2 , states has been found at 882.5 cm −1 for atomic chlorine. The intensity of this peak increased quadratically with increasing laser power. Therefore, the process involved one, and only one, photon in producing Cl. A model of photodissociation and photopredissociation is suggested, which could explain the dependence of the relative intensity on the laser frequency as well as the laser power. This model also predicts the population ratio of Cl in the two atomic states; the experimental results agreed with the predicted values.
