This paper presents and overviews the CHIMERA program package, which provides a user-friendly graphical interface between quantum chemistry and chemical kinetics programs. A wide variety of software tools exist for quantum chemical and reaction rate calculations and for kinetics analysis. However, to our best knowledge there is no commercial code available, which has a friendly graphical user interface (GUI) linking together all three types of software. CHIMERA has been initially designed to provide interface between quantum chemical programs (GAMESS and Gaussian) and chemical kinetics programs (UNIMOL, POLYRATE, and CHEMKIN) and to facilitate calculations of the rate constants for gas-phase reactions using transition state (TST) and Rice-Ramsperger-Kassel-Marcus (RRKM) theories. In the process of development, new features have been added or are planned to be included to extend the initial goal and create a unique multi-purpose program for chemical kinetics and thermodynamics analysis. The application of CHIMERA is based on the results of quantum chemical calculations of the components of the elementary gas-phase reactions, e.g. reactants, transition complexes and products, which constitute a (hypothetical) mechanism of the process under study. CHIMERA reads the required parameters from the outputs, calculates the reaction rates of individual elementary reactions and performs kinetics analysis of the complex reaction mechanism in a well-stirred reactor. The current version of the program can also compute thermodynamic potentials for initial reactants and products, as well as the energy, enthalpy and free energy of chemical reactions for the specified pressure and temperature intervals.
