Revised structure activity parameters derived from new rate coefficient determinations for the reactions of chlorine atoms with a series of seven ketones at 290Â K and 1Â atm

- Relative rate measurements resolve discrepancies over Cl + ketone rate coefficients.
- First determinations of rate coefficients for Cl + 3,3-dimethyl-2-butanone and 3-methyl-2-pentanone.
- Revised SAR proposed for Cl + ketones.
- Cl atom reactions can contribute to ketone removal from the boundary layer.
