| Abstract: | We present the results of analysis of the errors introduced by hot-band transitions 1110-0111, 0310-0111, 1200-1201 of the CO2 molecule and the absorption lines of the H2O and NO2 molecules in determination of the temperature and partial pressure of CO2, included in the gas mixture CO2: N2:H2O: NO2 at atmospheric pressure, by multiple-frequency laser probing using a CO2 laser tunable over the lines of the 0001-[1000,0200]I,II ground-state laser transitions. __________ Translated from Zhurnal Prikladnoi Spektroskopii, Vol. 74, No. 6, pp. 810–815, November–December, 2007. |
