End gas temperatures were measured by CARS(Coherent anti-Stokes Raman spectroscopy) technique in a constant volume combustion chamber. The temperatures of unburned and burned gas for premixed propane-air flame were measured for different initial temperature conditions. The measured temperature profiles were compared with predicted results of simulation performed using a 2-zone flame propagation model. The measured temperatures of the unbumed gas were distinguished from that of the burned at the flame sheet. The unbumed gas temperatures varied between 400 K and 600 K and the standard deviation of 10 measurements at each measuring time was about ±40 K. The predicted results of simulation confirmed the measured temperatures in each zone.<br/>
