On the Applicability of Redington's Method of Determination of Force Field to Bent XYZ Type Systems

Abstract

Abstract Force fields of NSF, NSCl, NSBr, SSO, HCO, HOF, HOCl, HOBr and HOI have been computed using Redington’s method. The angle parameters φ12, φ13 and φ23 are fixed through Fsteep critical point solution. The parametrised eigenvector matrices obtained are found to possess the properties predicted by Peacock et al. Mean amplitudes of vibration, Coriolis coupling constants, inertia defects and centrifugal distortion constants have also been calculated and compared with literature values. Redington’s approach is found to reproduce all the molecular constants with accuracies comparable with conventional methods.
