title: Electron attachment to fluorocarbon radicals.
abstract: Thermal electron attachment rate constants for a series of small fluorocarbon radicals (CF(2), C(2)F(3), 1-C(3)F(7), 2-C(3)F(7), C(3)F(5), CF(3)O) were measured from 300 to 600 K using the variable electron and neutral density attachment mass spectrometry method. With the exception of CF(2), for which no attachment was observed, all species exclusively underwent dissociative attachment to yield F(-). The magnitude and temperature dependences of the rate constants varied significantly between species; however, attachment was in all cases inefficient, never exceeding 2% of the calculated collisional value. The data are interpreted and extrapolated to conditions inaccessible to the experiment using a kinetic modeling approach to the electron attachment process.
