Gas -phase SN2 and bromine abstraction reactions of chloride ion with bromomethane: Reaction cross sections and energy disposal into products

The reaction cross-sections and the speed of product distribution are specified for the bimolecular gas phase nucleophilic substitution (SN2) reaction as a function of collided force. The outcome indicates that the exothermic SN2 reaction is not sufficient in comparison to the phasespace theory along with the ion dipole capture models.
