Abstract
It is shown that Qe, the partition function for a rigid rotor summed over even levels and Qo, summed over odd levels, have exactly the same asymptotic (power series in σ=ℏ2/2IkT) expansion. No information as to differences in thermodynamic properties due to spin and statistics can be obtained from this expansion. The exchange partition function, Qe—Qo, is calculated directly and used to give simple expressions for the differences in thermodynamic properties between the para, ortho, and equilibrium cases.Keywords
