Conclusions Anomalous values occur in the emissivity of explosion products of carbon disulfide-oxygen mixtures at relatively low pressures also (p0=0.03 atm). While within the spectral range of SO+O→SO2+hν recombination radiation (280–370 nm), in accordance with the results of [2, 3] the value exceeds unity, on the wings of the radiation band ε(λ)≪1. If nitrogen oxide is employed as an oxidizer instead of oxygen, the limiting emissivity becomes anomalously high in the spectral range of the chemiluminescent reaction NO+O→NO2+hν. It is proposed that at low CS2/O2 mixture pressure the radiation spectrum “wings” are connected with electron energy levels of SO2 molecules populated by the mechanisms of thermal multistep activation, due to which their density is less than the thermodynamic equilibrium value.
