Summary: The time profiles of vibrational molecular oxygen temperature $$T_v$$ measured earlier in experiments behind a strong shock wave were used for testing the theoretical and empirical models of thermal nonequilibrium dissociation of molecules. To do this, dissociating gas flows behind the strong shock wave front were calculated with account for these models. If the initial gas temperature behind the wave front $$T_0< 6.5\times 10^3$$ K, the models well describe changing the temperature with time. However, for $$T_{0}>7\times10^{3}$$ K neither of the models tested describes the measured temperature profiles satisfactorily. Using the empirical model proposed in the present study made it possible to satisfactorily describe the vibrational temperature evolution observed in experiments at temperatures up to $$11\times 10^3$$ K.
