Force Constants for F2CO and Thermodynamic Properties for F2CO and FClCO

Abstract
A set of force constants for F2CO has been calculated using the observed fundamental frequencies and a potential function consisting of valence force interaction terms and an additional term involving an interaction between the oxygen and fluorine atoms. The large values obtained for the interaction constant and the angle deformation constants were related to interaction forces between the terminal atoms. Also included in this paper are calculations of the thermodynamic properties of F2CO and FClCO.
