Description
Reduced partition function ratio of 32 compounds containing 3d elements are compared one with another on the basis of graphs of their temperature dependence. The evident general validity of the relationship between the partition function ratio and moleculer structural characteristics (force constants, molecular size, charge distribution) offers the possibility of qualitatively assessing isotope effects
