The thermNASA is a collection of software tools to read out thermodynamic data stored as NASA polynomials coefficients in both old conventional 7-coefficients format (used in Chemkin) and new 9-coefficients format (used in the latest CEA program).   Although the major applications of the thermodynamic data of chemical species, the equilibrium problems, are fully covered by the NASA-CEA program, thermNASA provides access to the each thermodynamic data by listing it in a tabulated form (like JANAF thermochemical tables, etc), calculation of the equilibrium constants for reaction, and evaluation of rate constants for the reverse reaction.
