H-3(+): the initiator of interstellar chemistry
2008 (English)In: International Journal of Astrobiology, ISSN 1473-5504, E-ISSN 1475-3006, Vol. 7, no 04-mar, 237-241 p.Article in journal (Refereed) Published
Second only to H-2, protonated molecular hydrogen, H-3(+), is the most abundantly produced interstellar molecule. Owing to its high reactivity and acidity, it plays the pivotal role in initiating interstellar chemical reactions, something which also reduces its steady-state concentration. Interstellar H-3(+) is not only destroyed in chemical reactions but also in dissociative recombination with electrons. The rate constant and mechanism of recombination have long been controversial, but great advances have been made during recent years, with the important consequence that the cosmic ray ionization rate in diffuse Clouds is now believed to be higher by an order of magnitude than previously assumed.
