Unimolecular Kinetics: Part 2: Collisional Energy Transfer and the Master Equation, Volume 43 in Elsevier’s Comprehensive Molecular Kinetics series, addresses collision energy transfer and the effects it has on gas phase reactions, particularly at low gas density. Such systems include combustion, industrial gas phase processes and atmospheric/environmental processes. The book also discusses The Master Equation to give a good overview of the mechanics underpinning unimolecular kinetics. This new volume will be of interest to researchers investigating gas phase processes which involve unimolecular reactions and the related intermolecular reactions.
