Summary:The feasibility of multiphoton excitation (MPE) and dissociation (MPD) of triatomic molecules is the subject of current experimental controversy. The most probable path approximation (MPPA) makes use of artificial intelligence algorithms to select the most important excitation paths within the semiclassical Floquet matrix, allowing efficient and accurate calculation of non-linear MPE quantum dynamics to very high order. An ab initio study of SO 2 using the MPPA indicates that collisionless MPD will not be achieved at laser field strengths under 20 GW/cm 2. The possibility of MPD at higher laser intensities is currently under investigation.
