Reaction Mechanism Generator (RMG)

Build status Codecov report Codacy report GitHub release Anconda Gitter RMG Website


This repository contains the Python version of Reaction Mechanism Generator (RMG), a tool for automatically generating chemical reaction mechanisms for modeling reaction systems including pyrolysis, combustion, atmospheric science, and more.

It also includes Arkane, the package for calculating thermodynamics, high-pressure-limit rate coefficients, and pressure dependent rate coefficients from quantum chemical calculations. Arkane is compatible with a variety of ab initio quantum chemistry software programs: Gaussian, Q-Chem, Molpro, Orca, Psi4, and TeraChem.
