The Automated Rate Calculator (ARC) software is a tool for automating electronic structure calculations and attaining thermo-kinetic data relevant for chemical kinetic modeling.

ARC has many advanced features, yet at its core it is simple: It accepts 2D graph representations of chemical species (i.e., SMILES, InChI, or RMG's adjacency list), and automatically executes, tracks, and processes relevant electronic structure calculation jobs on user-defined server(s). The principal outputs of ARC are thermodynamic properties (H, S, Cp) and high-pressure limit kinetic rate coefficients of species and reactions of interest.

ARC's mission is to provide the kinetics community with a well-documented and extensible codebase for automatically calculating species thermochemistry and reaction rate coefficients.
