## Abstract The rate coefficients for the reactions of Cl atoms with CH~3~Br, (__k__~1~) and CH~2~Br~2~, (__k__~2~) were measured as functions of temperature by generating Cl atoms via 308 nm laser photolysis of Cl~2~ and measuring their temporal profiles via resonance fluorescence detection. The m

Energetic H atoms produced by photolysis of gaseous HI react with CD,Br by D abstraction (1) and Br abstraction (2) and possibly also by the substitution reactions (4) and (5).
Hydrogen atoms, generated by the mercury (3P1) sensitization of Hz, were allowed to react with dimethyldisulfide in the temperature range of 25-155'C. The only retrievable product is methanethiol, formed in the primary metathetical reaction H + CH3SSCH3 k,' CH3SH t CH3S. The intermediacy of thiyl ra
The reaction Br + CH,CHO A HBr + CH,CO has been studied by VLPR at 300 K. We find k, = 2.1 x 10" cm3/mol s in excellent agreement with independent measurements from photolysis studies. Combining this value with known thermodynamic data gives k-, = 1 x 10" cm3/mol s. Observations of mass 42 expected
The kinetics of the reactions of Cl atoms with CH 3 ONO and CH 3 ONO 2 have been studied using relative rate techniques.
