It has previously been shown by experiments with a crossed-beam technique that the rotational energy distribution of OH (^2Σ^+) split from H_2O_2 is remarkably different from that of the same radical from H_2O. A theoretical distribution curve similar to the experimental one for OH from water has recently been derived by the present authors from a statistical model including the law of angular momentum conservation. In this paper, the above-mentioned theory is proved to be self-consistent by applying it to OH from H_2O_0. All kinds of angular momenta are taken into account in it without any simplification. The effect of the angular momentum initially Possessed by the parent molecule is also discussed in detail. The theoretical curve obtained for H_2O_2 gradually rises almost linearly at the lower rotational quantum numbers, in contrast to that calculated for H_2O, which ascends steeply up to a plateau. These different characteristic features fit well the respective experimental plots.
