Spectrometric Studies of Gas Phase Collision Processes
Abstract
Measurements have been made of the total radiation intensity from free jets of carbon dioxide and carbon that were excited in the source by a corona discharge. The radiation per molecule, obtained from the ratio of total intensity to source density, increases sharply when source temperature and pressure are such as the produce clustering in a jet of unexcited gas. We believe this enhancement may be due to interaction between aligned dipoles in adjacent cluster molecules. Measurements of the terminal rotational temperature of carbon monoxide and CO2, both pure in admixture with each other and/or argon indicate that CO always relaxes more slowly. There is no evidence of coupling between the rotational modes of the two species. Keywords: Gas dynamics, Infrared spectrometry, Rotational relaxation, Super-radiance, Collisions, Phase studies vapor phases.
