CARS signal of 20% of diluted in 80% of at 296 K and 1.85 amagat. The measurement is shown in the top panel (a). Differences between experiment and signal calculated by a sum of Voigt profiles (b), by a sum of speed dependent Voigt profiles (c), and by the KS-3D biparametric model (d) are, respectively, presented in the lower panels. These differences have been averaged over 0.7 ps in order to reduce the measurement noises.
CARS signal of 50% of diluted in 50% of at 296 K and 0.410 amagat. The dash line represents the experimental signal. The full line represents the signal calculated by the Voigt profile (a) and by the KS-3D biparametric model (b).
Same as Fig. 2 but for a mixture of with 20% of and a density of 0.893 amagat at room temperature.
Same as Fig. 2 but for a mixture of with 50% of and a density of 0.831 amagat and 503K.
Same as Fig. 2 but for a mixture of with 50% of and a density of 0.955 amagat and 703 K.
Densities determined by fitting measured CARS signals in function of the measured density, which is calculated from the gas state equation using the second term Virial correction and from measured pressures. The full squares are results obtained using the KS-3D biparametric model. The straight line represents results in which adjusted densities are equal to measured ones.
