Theoretical Results

Temperature and NO concentration can change dramatically during a vortex-flame interaction. In this paper, a vertically mounted buoyant hydrogen-nitrogen jet diffusion flame is used to study vortex-flame interaction. Single shot measurements of temperature by Coherent Anti-Stokes Raman Scattering (CARS) and of NO concentration by Degenerate Four Wave Mixing (DFWM) are used to investigate the temporal and spatial evolution of the flame. The results are compared with theoretical predictions. Temperature and mole fraction are presented in two-dimensional maps. Experimental and theoretical results are in excellent agreement.

Mixing Techniques

We review the results from two experiments that used resonant four-wave mixing (RFWM) techniques to investigate double-resonance transitions in NO. In the first experiment, laserinduced grating decay curves that reveal quantum beats due to the hyperfine structure of the A 2Σ, υ' = 0 state were observed and interpreted. In the second, multistate interactions between the L 2II1/ 2,3/2, υ = 8 and Q 2II1/ 2,3/2, υ = 0 states were investigated, and new assignments were made. The results highlight the potential of RFWM techniques for probing excited-state physics.
