deuspin.kida.uva.2016.zip	Type of chemistry : Gas-phase + Deuteration Publication: Majumdar et al. (2016) [DOI: 10.1093/mnras/stw3360; Full-text URL: https://arxiv.org/abs/1612.07845] Description:First gas-phase chemical network for studying deuterium fractionation in the interstellar medium called deuspin.kida.uva.2016. This is a first version of the kida.uva deuterated network developed from the kida.uva.2014 network. See the README and the papers for details. File updated on Jan 10 2018: minor corrections Additional note on April 13, 2021: The deuspin.kida.uva.2016 chemical network uses the rate coefficients for the H3+ + H2 reacting system presented in Table VIII of Hugo et al. (2009; J. Chem. Phys., 130, 164302). In recent years, some typographical errors have been discovered in this table. For example, the quoted rate coefficient for the ortho-H3+ + para-H2 -> ortho-H3+ + ortho-H2 reaction exceeds the Langevin value, and the reaction para-D2H+ + ortho-H2 -> para-H3+ + para-D2 is erroneously marked as forbidden while it is actually allowed by spin selection rules. Users of deuspin.kida.uva.2016 should therefore exercise caution when interpreting the results of models that adopt this network. New sets of rate coefficients for the H3+ + H2 system, derived from the Hugo et al. state-to-state data, have been presented in Sipilä et al. (2017; A&A 607, A26) and in Hily-Blant et al. (2018; MNRAS 477, 4454); we encourage the reader to adopt these rate coefficients instead. We thank Evelyne Roueff for pointing out this issue.	2017-01-16	deuspin.kida.uva.2016.zip 2017-01-16 Type of chemistry : Gas-phase + Deuteration Publication: Majumdar et al.
