✦ Synopsis

The vibrational relaxation of biacetyl following excitation by a highly intense laser pulse at lC.6 micron is studied. The changes in vibrational population are monitored by visible absorption from the ground electronic state to the excited n-n* state. The results indiatc that thermal disequilibrium persists for nt least 1O-5 seconds after the laser pulse at pressures in the range of I-40 torr.

The implimtions of these results for the use of high-power infrued lasers in inducing selective chemical reactions are briefly discussed.
