Popis: | Experimental data and analyses are presented for the determination of gas temperature by measurements of vibrational Raman scattering intensity ratios of Stokes Q -branch fundamental bands. The method is demonstrated for two thermal equilibrium experiments: (1) CO 2 (a gas well-suited for use in multi-component mixtures near ambient temperatures) in a test cell, and (2) N 2 (a gas well-suited for use at elevated temperatures) in a flame. This method of temperature measurement is of particular value for non-thermal equilibrium conditions, for which vibrational excitation temperatures can be assigned to each pair of vibrational level corresponding to observable Raman bands. |
