Abstract

The spectral distribution of the pulsed, flash initiated Cl + HI → HCl(ν) + I chemical laser (3.6μ-4.0μ) was studied in both free running and grating selected systems. New transitions in both cavities are reported. The relative populations of the lasing HCl vibrational levels were measured using the grating selection technique. The relative distributions were found to be N3/N2 = 1.10 to 1.29 and N2/N1 = 2.23 to 2.32. A computational comparison between the chemical laser results and previous measurements by the infrared chemiluminescence method is made in view of vibrational V-R,T,V′ relaxation processes which may change the nascent population distribution.
