Abstract
The formulas of Bigeleisen and Mayer for the free energy difference between isotopic compounds are used to derive formulas for the similar differences in entropy, enthalpy, and heat capacity. Tables of these functions are calculated. The analogous quantities in the ``thermodynamics of reaction rates'' are discussed. Several useful formulas for the entropy differences of isotopic molecules are derived.Keywords
