Using the Saha equations and spectroscopic constants, the computer program in this report calculates the species populations of diatomic molecules, neutrals, ions, and electrons in a plasma. The code considers the equilibrium of a two-element, chemically reacting plasma, by calculating the partition function for each species. By rederiving theoretically, as the JANAF tables do, the thermodynamic properties of a rocket propellant, but using extended excitation levels, the program can estimate above 6000 K performance of advanced propulsion concepts.
