Coherent antihyphen;Stokes Raman (CARS) spectra are reported for the nascent products of visible laser photolysis of CF3NO. The results indicate a high degree of rotational excitation in both CF3and NO fragments following Cndash;N bond cleavage. The rotational band shapes observed for both photoproducts are consistent with those predicted from simple prior statistical calculations and correspond to Boltzmann temperatures in excess of 1100 K. This first detection of the CF3radical by a Raman technique confirms earlier low resolution infrared assignments of the ngr;1symmetric Cndash;F stretching vibration and yields an improved value of 1088.6plusmn;0.5 cmminus;1for this fundamental mode. With several simplifying assumptions, band contour calculations are used to estimate changes inBandCrotational constants for this transition.
