Evolution of the contribution of mixed methanol (green), segregated methanol (purple), and methanol forming a type II clathrate hydrate (blue) to the total area of the C–O stretching band of CH₃OH during warm-up of a pre-cometary ice mixture (E11), according to fit with three Gaussians of the IR band. Temperatures for which the fit was done are indicated. Figure 8 shows three selected fits as an example.
