The infrared multiphoton dissociation of chlorodifluoromethane is studied in a dc electric field. The reaction yield is measured as a function of the laser energy fluence, the CF2HCl pressure, and the electric field strength in the range 0⩽E⩽5.4 kV cm−1. At low fluence (F<1J cm−2) and intensity, under essentially collision free conditions, the multiphoton dissociation is strongly enhanced by the electric field. This is tentatively explained by a breakdown in the angular momentum selection rules caused by the applied field.
