The feasibility of multiphoton exitaton (MPE) and dissociation (hiPD) of trktomic molecules is the subject of current e~perimenral controversy\_ The most probable path approximation (MPPA) makes use of artificial intelligence algorithms to select the most important excitation paths within the semicl

β¦ Synopsis
SO? molecules excited under essentialIp collision-free conditions by intense (>20 G\V]cm') COP laser pulses @ve off a broad UV-visible luminescence through inverse electronic relaxation. Unlike in lager polyatomics, the infrared multiphoton escitation process is controlled by the laser intensity and not the laser fluence.

We investigated the infrared multiphoton excitation of SO2 in bulk samples and in a supersonic jet with the 9R1,22), 9R(32), and 9P( 32) CO\*-laser lines. Coherent anti-Stokes Raman spectra reveal unambiguously that only the v,-mode at II5 I .3 cm-' is actually pumped; no 2vl overtone pumping at 103
The dependence of collisionless multiphoton excitation on the laser polarization is theoretically discussed and esperimentally observed in SFe irradiated by a TEA COP laser.
