The formation of methyl cations from the dissociation of energy selected methyl halides near their dissociation thresholds was investigated. High-resolution pulsed field ionization-photoelectron (PFI-PE) and PFI-PE-photoion coincidence (PFI-PEPICO) techniques were used for the analysis. A highly reliable value of the heat of formation of these compounds were obtained from the results.
