โœฆ Synopsis

The photodissociation of acetyl chloride at 248 nm has been investigated by the technique of photofragment translational spectroscopy. A comparison of the translational energy distributions required to fit the chlorine atom and the acetyl radical indicates that a significant fraction ( = 35%) of the CH&O fragments undergo secondary decomposition to CHs and CO. From analysis of the center-of-mass translational energy distributions a value of 17 f 1 kcal/mol for the barrier height to acetyl radical dissociation has been determined.

Due to the overbinding that is inherent in existing local approximations to the density-functional formalism, certain reaction energies have not been accessible. Since the generalized gradient approximation significantly decreases the overbinding, prospects for density-functional based reaction dyna
