摘要: Abstract We present a study of the spontaneous Raman spectra 12CH4 from 1200 to 5500 cm−1 at various temperatures. This is interest fundamental as well practical point view with regards temperature diagnostic in hydrocarbon combustion. The investigation shows that are very sensitive and complexity methane not an obstacle use probe molecule laser-diagnostic techniques. Our consists determining polarisability parameters 12CH4, unknown time, recorded pressure less than one atmosphere minimize problem line-mixing. method technique based on spectroscopy may be applied measurements uni-element rocket combustion chamber using methane–oxygen propellants.
