The relation of Bigeleisen and Mayer for reduced partition ratios of isotopic molecules is rewritten and extended, giving the possibility of prompt and more exact statistical calculations with common tables of functions. for a number of molecules of the types XY/sub 4/ (tetrad) and XP/sub 3/ (pyramid), with Y = O/sup 16/ and O/sup 18/ partition function, ratios are calculated in two approximations and exactly for 273.l5 deg K and 300 deg K. The accuracy of another approximative formula of Bigeleisen is practically sufficient for the treated molecules. From the partition function ratios result the equilibrium is constant for all possible exchange reactions between these molecules. (auth)
