摘要	The C-13-selective infrared multiphoton dissociation of CF3CH2Cl has been studied by analyzing the distribution of C-13 concentrations of the main products CF2=CHCl, CF2=CH2, CF2=CHF, C2F6, and the trace products CF3CH2CF3 and CF3CH=CHF3. The mechanism mainly concerns the dissociation of energized CF3CH2Cl, the collisional stabilization of excited CF3CH and CF3CH2 and the recombination of the nascent radicals. Mo signifi cant radical-molecule reactions degrade the intrinsic C-13 dissociation selectivity. High C-13 production yield and C-13 concentration can be attained at a laser fluence of 1.6 J/cm(2). Such low fluence can be used to improve focus condition and enhance photon utilization efficiency for practicable C-13 separation.
