✦ Synopsis

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 from ketene suggest a rapid secondary reaction: Br + CH,CO 5 [CH,COBrl* 5 HBr + CH,CO

## Abstract The multiple‐channel reactions Br + CH~3~SCH~3~ → products are investigated by direct dynamics method. The optimized geometries, frequencies, and minimum energy path are all obtained at the MP2/6‐31+G(d,p) level, and energetic information is further refined by the G3(MP2) (single‐point)
