“…Individual line-broadening coefficients for a particular spectrum were obtained using nonlinear least-squares fitting which we have discussed previously (1). Since accurate line positions and relative intensities of hyperfine components are now available for the NO v ϭ 1 4 0 band (6), we incorporated this information in the fits.…”

“…We recently completed a study of the temperature dependence of N 2 broadening of the NO vibrational fundamental band (1) and in that paper gave the rationale for the work in terms of monitoring the "health" of the Earth's atmosphere. Since the atmosphere consists of about 21% molecular oxygen, it is also necessary to know the broadening by O 2 of NO vibration-rotation lines.…”

A six-level model is developed and used to study the effects of collisional energy transfer and dephasing on electronic-resonance-enhanced coherent anti-Stokes Raman scattering ͑ERE-CARS͒ in nitric oxide. The model includes the three levels that are coherently coupled by the three applied lasers as well as three additional bath levels that enable inclusion of the effects of electronic quenching and rotational energy transfer. The density-matrix equations that describe the evolution of the relevant populations and coherences are presented. The parametric dependencies of the ERE-CARS signal on collisional energy transfer and dephasing processes are described in terms of both a steady-state analytical solution and the numerical solutions to the governing equations. In the weak-field limit, the ERE-CARS signal scales inversely with the square of the dephasing rates for the electronic and Raman coherences. In accord with published experimental observations ͓Roy et al., Appl. Phys. Lett. 89, 104105 ͑2006͔͒, the ERE-CARS signal is shown to be insensitive to the collisional quenching rate. Parametric dependencies on quenching, rotational energy transfer, and pure electronic dephasing are presented, demonstrating reduced collisional dependence for saturating laser fields.
