Notes. We note that $n_{H_{2}}$ $\[n_{\mathrm{H}_2}\]$ is the H₂ density, A_v the extinction coefficient, ζ the cosmic-ray ionization rate, T_g, T_d the gas and dust temperature, respectively. Besides E_diff/E_bin is the diffusion to desorption ratio, N_act the number of chemically active layers, and a corresponds to the energy conversion parameter in the chemical desorption scheme of Garrod et al. (2007).
