Rate coefficients for the reaction ${\mathrm{CH}}_3\mathrm{SH}+{\mathrm{CH}}_3{\mathrm{OH}}_2^{+}$ as a function of the temperature when using the CCSD(T)/aug-ccpV(Q+d) Z energy values (see text). The partial rate coefficients for channel (3 a) leading to (CH₃)₂SH⁺+H₂ O (red line), The channel (3 b), leading to ${\mathrm{CH}}_3{\mathrm{SH}}_2^{+}+{\mathrm{CH}}_3\mathrm{OH}$ OH (blue line), back-dissociation (cyan line), and the global capture rate coefficient (dashed black line), are shown.
