Excited-state Structure and Dynamics of Nitric Oxide probed by Resonant Four-wave Mixing Techniques

Abstract

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 ²II_{1/ 2,3/2}, υ = 8 and Q ²II_{1/ 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.
