Notes. (a) CS-He rates from Lique & Spielfiedel (2007). (b) Collisional rates derived from those of OCS (Green & Chapman 1978) and from the IOS approximation for a 3Σ molecule (see Corey & McCourt 1983; Corey 1984). (c) HCS+-He rates from Monteiro (1984). (d) OCS-H2 rates from Green & Chapman (1978). (e): HC3N-p-H2 rates from Wernli (2007). (f) HC5N-H2 rates estimate from the desexcitation rates of Deguchi & Uyemura (1984).
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.
