Molecular constants of some bent symmetrical XY2 molecules

Abstract
On the basis of a revised set of symmetry coordinates, all the force constants (General Quadratic Valence Force Field) of 16 bent symmetrical XY2 type of molecules have been evaluated afresh by the Wilson's F‐G matrix method using the Raman and infrared spectral frequencies. Certain simplifying considerations involving molecular dynamics have been made use of in solving the secular equation. The mean amplitudes have also been calculated at 298.16° K by Cyvin's method using the present values of the force constants.
