Vibrational temperature-velocity correlation

Temperature-Velocity Correlation Measurements for Turbulent Diffusion Flames from Vibrational Raman-Scattering Data... 

These include temperature, major constituent densities, gas velocity, and correlations of these properties. We discuss here the advantages and limitations of various potential light-scattering probes, and illustrate these with recent results for vibrational Raman scattering flame diagnostics. 

Figure 19. Velocity auto-correlation functions for the three intramolecular vibrations of water molecules at supercritical temperatures (a) 771 K, 1.284 g/cm (b) 673 K, 0.166 g/cm. Q, Q2, and Q3 denote the symmetric stretching, bending, and asyimnetric stretching modes, as illustrated on the inserts.
