Title: On the Origin of the Band Structure Observed in the Collision-Induced Absorption Bands of CO2
Published: April 01, 2003
Abstract: A more complete analysis of the dimer structure observed on top of the collision-induced absorption bands of carbon dioxide is presented. The analysis treats the carbon dioxide dimer as an asymmetric rotor with a and b type infrared transitions and rotational constants similar to that observed in a molecular beam spectrum of the dimer, in contrast to a previous modeling which considered the dimer as a prolate symmetric rotor with a pure a-type infrared band. The analysis does not require invoking a large change in the C C bond length previously determined in the molecular beam study.
