Abstract

The chemiluminescence spectra of chlorine atom recombination reactions have been studied by several researchers since sixties.¹-³ Nevertheless, a full quantitative description of the chemiluminescence spectra is not available in the literature yet. In this report, the chemiluminescence spectra of chlorine atom recombination reactions were recorded by the laser photolysis/luminescence detection method as shown in Figure 1. With the help of the recent advances in the assignments of the energy states of several bound electronic excited states of chlorine molecules,⁴ the full recorded spectra were quantitatively simulated as a superposition of the emission spectra of both A and B states as shown in Figure 2. The rotational and vibrational temperatures and the relative population of the two electronic states were obtained accordingly.
