General Model of Anharmonic Interaction Force Constants in Polyatomic Molecules

摘要

A model, previously postulated in a twohyphen;dimensional form and applied to the discussion of anharmonic stretchndash;stretch interaction force constants in triatomic molecules, has been extended to the polydimensional case. In this form it has been used to discuss the anharmonic interaction force constants coupling the stretching and bending coordinates. Numerical values of the model parameters have been evaluated for CO2and HCN.
