FIG. 1.

Six-level model for ERE-CARS in NO.

FIG. 2.

Squared electronic coherence amplitudes for the ERE-CARS signal transition in atmospheric-pressure flows of 1000 ppm NO in diluted with (a) and (b) . The origin of the time axis corresponds to the time when the peak of all applied pulses reaches the molecule. The relevant collisional parameters listed in Table I correspond to the experimental conditions investigated in Ref. 2.

FIG. 3.

(a) Raman coherence and (b) squared electronic coherence for various values of the quenching rate, with the electronic dephasing rate and RET rate being fixed at the values and , respectively. The dashed, solid, and dotted curves correspond to , , and , respectively. (c) Variation in the time-integrated signal for quenching branching ratios of 0.4 (solid) and 0 (dot-dashed).

(a) Raman coherence and (b) squared electronic coherence for various values of the RET rate, with the electronic dephasing rate and quenching rate being fixed at the values and , respectively. The dashed, solid, and dotted curves correspond to , , and , respectively. (c) Variation in the time-integrated signal as a function of RET rate.

FIG. 5.

(a) Raman coherence and (b) squared electronic coherence for various values of the pure dephasing rate, with the RET rate and quenching rate being fixed at the values and , respectively. The dashed, solid, and dotted curves correspond to , , and , respectively. (c) Variation in the time-integrated signal as a function of the pure dephasing in the electronic transition.

Tables

Generic image for table
Table I.

Experimental mixture conditions from Ref. 2 and corresponding collision-model parameters used in simulations presented in Fig. 2. The bracketed values for the RET rates in mixtures containing represent two limiting cases where the RET rate is assumed to be either 15% less (Ref. 13) or 25% more (Ref. 15) than the RET rate.
