AbstractDifferent cut-off criteria of partition functions have been utilized in order to evaluate the con­tribution of electronic excitation to thermodynamic properties of high temperature gases (5000 °K to 35 000 °K, 10-2-10 atm). It is shown that properties of single species are strongly affected by the cut-off criterion adopted, i. e. the contribution of electronic excitation to these properties is important. It is also shown that the reported absence of this contribution to total enthalpies and specific heats of plasmas is the result of an almost complete compensation between "reactional" and "frozen" terms which are all dependent on electronic excitation.

Thermodynamic functions of plasmas of alkali metals and of their components - diatomic molecules, atoms, simply charged ions and electrons - are calculated in the temperature range 298.15 °K -10000 °K. At this it is supposed, that the plasma is in thermodynamic and chemical equilibrium and in an ideal gas state.The internal partition functions of the components of the plasmas are calculated by summation term by term up to characteristic quantum numbers. These characteristic quantum numbers are determined by graphic and calculating methods.The thermodynamic functions of alkali metal plasmas and their components are discussed and compared with results calculated by approximative methods.
