Progress in Reaction Kinetics and Mechanism is an open access, peer reviewed, international journal that presents results from the fields of kinetics and mechanisms of chemical processes in the gas phase and solution of both simple and complex systems. Primarily a vehicle for publishing original research papers and occasional reviews in reaction kinetics and mechanism, its scope is very wide, covering atoms, small molecules and free radicals in the gas phase (relevant to combustion, atmospheric chemistry, etc.), solution reactions (including those of organic molecules, polymers and inorganic complexes, the latter when directed towards developing energy storage devices and new catalysts for effecting established reactions but at lower energy cost and higher efficiency). A number of papers are on computational chemistry, notably the use of Density Functional Theory to explain or predict the course of chemical reactions of all types.
