Figure 19. Measured temperature dependence of the pressure quadratic coefficients Cs of the continuum absorption at the (a) 10P(20), (b) 10P(24) and (c) 10P(30) CO2-laser emissions. Dashed lines correspond to least square fits based on equation (25). Solid lines correspond to best fits on the basis of equation (29).Dimer model: Suck S.H., Kassner J.L., Jr., Jamaguchi J.
