Abstract

In order to validate spectroscopic parameters of CO for in situ laser spectroscopy combustion diagnosis, a near-infrared laser spectrometer was utilized to determine basic line parameters of 3 selected transitions around 1.56µm at temperature up to 1000K. The line strengths, and N2 broadening coefficients were deduced from the recorded spectrum. The temperature dependence of the line strengths were experimentally analyzed and compared with theoretical predictions.
