Mixed Mode Contributions to Absorption in CO(2) at 10.6micro.
A rise of temperature in a molecular system causes the higher energy levels to become more populated. For the case of CO(2) absorption (or, in a lasing medium, gain) calculations based only on single line considerations are sometimes inappropriate as the contributions from some higher energy levels can be appreciable. This paper summarizes this effect for 10.4micro band of CO(2) . The calculations are compared with the experimental measurements of others.
