The survival probability for photodissociation of ozone in the Hartley band is computed using classical trajectory techniques with Wigner sampling of the initial conditions. In the general Cs symmetry, the survival probability exhibits notable recurrences, in qualitative agreement with quantum dynamics results. The present work confirms the analysis by Johnson and Kinsey [J. Chem. Phys. 91, 7638 (1989)], who postulated the role of unstable quasiperiodic orbits in the experimental autocorrelation function.
