Abstract

A quasi-classical trajectory calculation is performed to simulate formaldehyde decomposition following S₁ → S_o internal conversion. No mode specificity is observed in the unimolecular decay rates. Each of the trajectories exhibited chaotic motion. These findings suggest that the S₁ → S_o internal conversion step does not prepare long-lived vibrational states in ground-state formaldehyde.
