Abstract
Certain correction terms applying to the rigid‐rotator harmonic‐oscillator approximation for the thermodynamic functions have been worked out in a general form. Tables of the functions which appear in these correction terms are presented. These results have been applied in the calculation of the thermodynamic properties of nitrous oxide. A comparison of the present procedure and that of Mayer and Mayer for diatomic molecules is given.Keywords
