Notes. Radicals are marked with a dot at the radical site. * indicates a species that was already present in the network, which we note here for completeness. The values for binding energies are extrapolated from similar species or those with similar functional groups in the network, and are based on the work of Garrod et al. (2008). The values for proton affinities are taken from multiple sources (a) Hunter & Lias (1998) and (b) Garrod & Herbst (2023).
