Rate constants for reactions of SiFz radicals have been measured at 2 Torr in a high-temperature fast-flow system. The bimolecular reaction rate constant for SiF\*+F, over a temperature range of 282-617 K can be expressed as (1.0+0.25)X IO-"exp[ -(1850~2OO)lRT] cm3 molecule-' s-', where R is incal m
