Microwave Spectrum of Formaldehyde III. Vibration-Rotation Interaction

Abstract
The centrifugal distortion constants and the inertia defects necessary for the analysis of the microwave spectrum of formaldehyde molecule were calculated by the vibration-rotation theory. Nielsen's formulation was used throughout together with the useful relations found by the present authors. The calculated centrifugal distortion constants, inertia defects and Coriolis coupling constants fit well to the experimental values.
