Simulation of nitrogen Raman vibrational-rotational band for temperature determination

摘要

This paper presents a technique for simulation the nitrogen Raman vibrational-rotational band, which is one of the main gaseous components of combustion products. The deviation of the temperature values obtained by fitting the spectra from the reference data was less than 3 K in the range of 300-600 K. It is shown that neglecting of the effects of vibrational-rotational interaction leads to an increase in the measured temperature by 3 K.
