Abstract
New high-temperature measurements of collisional linewidths of the Raman Q branch of nitrogen have been performed at 1700–2400 K with stimulated Raman spectroscopy in a tungsten filament. We fitted these data together with previous data obtained in the 295–1500-K range to redetermine the parameters of the relaxation models used in coherent anti-Stokes Raman spectroscopy thermometry. The improvement in the accuracy of the temperature measurement has been checked. Semiclassical calculations of linewidths in the 1700–2400-K range agree with the experimental data and have been extended to even higher temperatures.
