Table A.1:

Reactions used in the model. The rate coefficients are given for 7 K. Reaction rates less than 10-15 cm-3 s-1 are not taken into account in our models. Reference (1) corresponds to Gerlich (1990), references (2)-(4) correspond to Hugo, OSU 07, and this paper respectively. For OSU 07, branching ratios involving spin states have been infered from quantum mechanical rules. For reactions involving grains, a grain radius of 0.1 $\mu $m and a sticking coefficient of 1 have been considered. (5) Datz et al. (1995b) (6) Datz et al. (1995a), (7) Zhaunerchyk et al. (2008), (8) Larsson et al. (1997), (9) Molek et al. (2007).

1 $k'_{\rm CO}$ and k'N2 indicate that the $k_{\rm CO}$ and kN2 rates have been corrected for the higher reduced mass of the system because of the presence of H2D+ instead of H3+. Similarly, k'' and k''' are given for D2H+ and D3+ isotopologues.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
