Spectroscopy of shock-heated methane using nonlinear IR spectrography

The methane absorption spectra were obtained behind a shock wave (temperature 1370 K), at 293 K by devised nonlinear IR spectrograph. The spectra calculated on the basis of HITRAN92 data accord with experimental ones. The possibility of temperature determination of methane containing mixture on absorption spectra shape is discussed.© (1996) COPYRIGHT SPIE--The International Society for Optical Engineering.
