Paper Abstract

During recent years we studied the dynamics of collisionless SF6 and NH3 molecules' excitation by TEA CO2 laser radiation. The main purpose of this research was to explain why the molecules, which have no exact resonance with the CO2 laser field, absorb one or several IR quanta. We made measurements in a free supersonic jet and in a cell. Exciting energy densities were among 10-2 and 2.0 J cm-2. The fraction of molecules excited from individual rotational levels was measured and its dependences on the CO2 laser frequency and on the energy density were investigated. We present the comparison of the experimental data with theoretical calculations, and questions that still remain unclear are discussed.
