Abstract
From a consideration of the form of the bending potential in internal coordinates for a1II electronic state of a linear molecule, the equations for calculating the bending vibrational frequencies and Renner parameters of different isotopic molecules are obtained, and relations connecting the Renner parameters of different isotopes are derived. The recent results for the GlΠu and H1Πu states of acetylene isotopes [5] are consistent with the theory, but it is not possible at present to determine the sign of ϵ55 for the H1Πu state from the C2HD isotope effect on ϵ44. © 1981 Taylor & Francis Ltd.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
