Abstract

We report on the application of degenerate four-wave mixing (DFWM) spectroscopy to the study of the temperature dependence of the2B1(k″ = 0)-2A1(k′ = 1) Douglas-Huber band of NO2up to 473 K. Measurements were performed in a static optical cell filled with pure samples at a pressure of 0.1 mbar. The possibility of selecting well-isolated spectral features for thermometric application using the Boltzmann plot method (BPM) was investigated. Experimental data indicated that at T ≥ 393 K the use of BPM method has to be restricted to transitions with rotational quantum numbers N ≤ 15. Temperature predictions based on the BPM were compared with concurrent measurements performed with a thermocouple. Copyright © 2002 John Wiley & Sons, Ltd.
