Quantitative Raman Spectroscopic Determination of the Composition, Pressure, and Density of CO2-CH4 Gas Mixtures
Figure 6
The variation in D (a) and Δ (b) within CO2-CH4 gas mixtures as a function of density and composition. D = υp − υ0 is the difference between the υ1 peak positions of CH4 at elevated pressure (υp) and near-zero pressure (υ0); Δ represents the separation between bands in the Fermi diad of CO2.
