✦ Synopsis

Charge-transfer reactions of Ar+ with CH,Cl,_, (n= l-3) at thermal energy have been studied by using a flowing-afterglow apparatus coupled with a low pressure chamber. Dissociative charge-transfer leading to CH: (91 k 5%) CH&l+ (95 k 2%), and Ccl+ (69 f 3%) are major product channels for CH,Cl, CH#&, and CHC&, respectively. Total rate constants are ( 1.3 f 0.5) X 1 Oe9, (0.97 k 0.42) x 10m9, and ( 1.2 k 0.6) x 10m9 cm3 s-' for CHsCl, CH2C12, and CHC13, respectively. These values amount to 57%-80% of the collisions rate constants estimated from either the Langevin or ADO theory.
