Abstract

General points of the theory of isotope substitution are applied to an analysis of the isotope substitution effect for the substitution ¹³C₂H₄←¹²C₂H₄ in the ethylene molecule. On the basis of the isotope relations so obtained, numerical predictions of band centers and the most significant rotational, centrifugal, and resonance parameters are made here for the first time for the four lower vibrational states of the ¹³C₂H₄ molecule, which can be used to analyze the complicated vibrational-rotational structure of the above-mentioned vibrational states.
