abstract = "The study is dedicated to testing of Mars entry physicochemical models starting from recent 96%CO2 -4%N2 shock tube experiments documented in the literature. Absolute measurements of the radiation in the peak and plateau regions, for C2 Swan Δv = -1 and CN Violet Δυ = 1 bands, are compared with radiative signatures rebuilt within conventional formulation in the frame of the common assumptions on chemical nonequilibrium and two temperatures. Two different chemical-kinetic reaction models, one proposed by Park [1] and its recent update by Lee [2], are considered to enhance the analysis of the relaxation features in the flow. Calculated temperature profiles have shown a quite negligible sensitivity to model differences. However, density profiles were found significantly affected, consistently with discrepancies in the adopted data. Comparisons with experiments have shown good agreement for CN Violet Δυ = 1 radiation. Disagreements for C2 Swan Δυ = -1 bands radiation are discussed. Analysis of discrepancies observed for C2 radiation has emphasized the specific features induced by the models of the relaxation dynamics.",
