Broadening coefficient of line at 600 K (a) and of line at 900 K (b) of diluted in vs concentration. The collisional broadening coefficient using the linear mixing rule (broken line) is also reported for comparison [cf. Eq. (5)]. The dots represent the values of the broadening coefficients adjusted from experiments.
Broadening coefficient of diluted in vs concentration calculated from kinetic impact equation [cf. Eqs. (7) and (8)] at 10 amagats. The dots correspond to the collisional broadening coefficient [cf. Eq. (5)]. (a) line at 600 K. , (⋯), (- - -), (– –), (—). (b) line at 900 K. , (⋯), (- - -), (– –), (—).
CARS signal of 20% of diluted in 80% of at 900 K and 9.25 amagat. The broken line represents the experimental signal. The full line represents the signal adjusted by the Lorentzian model (a) and the signal adjusted using the KS-1D model with memory parameter (b).
CARS signal of diluted in . The broken line represents the experimental signal. The full line represents the best signal adjusted using the KS-1D model. (a) CARS signal with 5% of diluted in 95% of at 600 K and 9.56 amagat. The value of the memory parameter is 0.90. (b) CARS signal with 50% of diluted in 50% of at 900 K and 9.34 amagat. The value of the memory parameter is 0.93.
