Experimental prefactor ν, most probable adsorption energy Eads and size of the adsorption energy distribution δEads as taken as the full width at half maximum, for CH3CN and CH3NC adsorbed on α-quartz (0001), and crystalline or compact amorphous water ice surfaces.

| Amorphous water ice | CH3NC | 5 × 1016 ± 0.5 | 490* | 490* | 25 | 20 |

Notes. Distinction is made between adsorption energy at high coverage (0.7–1 ML) and low coverage (<0.3 ML). Values denoted with * should be considered with caution since the sublimation of the supporting water ice layer plays an important role in the observed desorption features.
