Prominent sources of molecular opacity under disequilibrium chemistry. The atmospheric pressure at which the vertical wavelength-dependent optical depth of species x reaches unity, p(τ_x(λ) = 1), is shown across the infrared. Several molecules included in both the kinetic model and the opacity database that do not reach τ_x(λ) = 1 by the 10 barlevel (e.g., C₂H₂) are omitted. See Paper I (Fig. 20) for opacity contributions due to species not included in the kinetic model (heavy-metal oxides, atoms, etc.). All opacities are plotted at a spectral resolution of R = 1000. Four equatorial regions are considered: (i) the antistellar point, (ii) the morning terminator, (iii) the substellar point, and (iv) the evening terminator. For comparison, the τ(λ) = 1 surface due to clouds from Paper I is overlaid.
