Spectra of Stimulated Emission in the Hydrogen-Fluorine Reaction Process and Energy Transfer from DF to CO(2).
The spectra of stimulated emission, observed in the process of the H(2) + F(2) ? HF and D(2) + F(2) F(2)? DF reactions, were investigated and compared. The stimulated emission in the vibrational transitions up to 6-5 for the HF molecule and up to 9-8 for the DF molecule was discovered. It was found that the emission energy in the transitions of 2-1 and 5-4 bands in the H(2) + F(2) mixture was the highest possible. In the D(2) + F(2) mixture the emission energy maxima correspond to the 3-2 and 8-7 bands. The presence of the two maxima reflects the fact that the two types of chemical reactions contribute to the population inversion creation. One is a F + H(2)(D(2)) reaction, the other is a H(D) + F(2) reaction. By analyzing the characteristics of the chemical laser in which the energy exchange between the DF and CO(2) molecules takes place, the energy-transfer rate constant was estimated with the value being equal to (1.5 +/- 0.5) x 10(-12) cm(3) sec(-1).
