ABSORPTION IN CO2 AT 10.6 μ WITH ROTATIONAL LINE OVERLAP

Abstract
The results of a calculation and measurement of the absorption of 10.6‐μ laser radiation by CO2 at high pressures are described. It is shown that the effect of rotational line overlap becomes significant at pressures slightly greater than 1 atm. At 8 atm, for example, the calculated absorption coefficient is twice that without including line overlap. Measurements, however, indicate a larger effect than is predicted.
