(Left) TPD curves of SO₂ deposited at 80 K on c-ASW at different coverages (brown curve, 4.65 ML; red curve, 2.50 ML) in the multilayer regime, together with the corresponding zeroth-order fits (dashed blue and green lines, respectively). (Right) Logarithm of the corresponding TPD curves as a function of the inverse sample temperature, with corresponding linear fits (dashed lines). The extracted values of E_ads and ν are reported in the panels.
