The abstraction of hydrogen/deuterium from CH3CH2C1, CH,CHDCl, and CH,CD,Cl by photochemically generated ground-state chlorine atoms has been investigated over the temperature range of 8-94ยฐC using methane as a competitor. Rate constant data for the following reactions have been obtained: (1) CH,C&C
The I3C shielding of the isotopomers CH,Cl, CH,DCl, CHD,Cl, and CD,C1 has been calculated for a range of temperatures from an self-consistent field (SCF) shielding surface computed by Buckingham and Olegario. It is found that each successive deuterium substitution increases the shielding by about 0.
