Variable ED induced changes in the translucent cloud. Comparison between Models full (solid lines) and noEd (dotted lines) for selected species including those with gas-phase abundances most affected by ED changes via the H-bond rule: inorganic in panel (a), carbon chains in panel (b) and other organic in panel (c). Panel (d) shows the growth of ice mantles on the grains, with thinner lines indicating smaller grains. The changes are caused by lack of strong H-bonding on bare grains in Model full. -- astro-ph.GA
