Infrared Spectrum and Molecular Constants of Carbon Dioxide. Part I. ν2 of C12O216 at 15μ

Abstract

The vibration-rotation band associated with the fundamental bending vibration of CO2 has been reinvestigated with a 2000 lines/inch grating mounted in a vacuum chamber. The P and R structure has been resolved up to J=60. The molecular constants have been evaluated and they are summarized in Table II. Within the accuracy of the present data it has not been possible to detect any change in the centrifugal stretching constants between the two states involved in this transition.
