Abstract
We apply the quantum Monte Carlo method with effective core potentials to the propargyl radical, $C_{3}H_{3}$, and its cation and anion. Properties computed and compared with other theoretical and experimental results include heats of formation, electron affinity, and ionization potential. The study of $C_{3}H_{3}$ is important in understanding soot formation in hydrocarbon flames. Other systems that will be discussed are acetylene and ethylene. Binding/atomization energies for the latter systems are found to compare very favorably with experiment. This work was supported by the Director. Office of Energy Research.
