Abstract: Abstract In this chapter we study the shock wave structure in a rarefied polyatomic gas by using the ET14 theory. We show how the ET14 theory can overcome the difficulties encountered in the previous approaches: Bethe-Teller approach and Gilbarg-Paolucci approach. Firstly, the predictions derived from the ET14 theory are shown and compared with the results from the NSF theory. Secondly, the Bethe-Teller theory is reexamined in the light of the ET14 theory. Lastly, comparison between the theoretical predictions derived from the ET14 theory and the experimental data is made, where we show a very good agreement. We are able to explain in a unified manner the three different shock wave profiles Types A, B and C for increasing Mach number.
