Filling of the Atmospheric Transmission Window Due to Emission from Very High Rotational Levels of NO and O3,

Abstract

The Quantum-Mechanical Spectator Model or Impulse Approximation (IA) thus far has been used to study the collisions between fast projectiles and targets having little or no internal excitation. It is suggested that IA be applied to collisions of low energy (thermal) projectiles with targets having large internal excitation. This extension is the mechanism proposed for the R-branch bandheads observed in vibration-rotation (V-R) band emission from the high-altitude atmosphere and flow tube laboratory experiments under circumstances which rule out the presence of hot atoms. The implications of V - R transfer for radiance in the atmospheric transmission window are discussed.
