(ii) the sublimation enthalpy at 298K (∆H sub,298K ), (iii) the enthalpy change associated with heating the gas phase solute from 298K to temperature T (∆H g,298K→T ), and (iv) the enthalpy required to dissolve the solute from the gas phase into the organic solvent (i.e. the solvation enthalpy) at temperature T (∆H solv,T ). Some of the enthalpy terms can further be replaced by the temperature difference and the heat capacity of the solute in the solid phase (C p,s ) and in the gas phase (C p,g ) (see Eq. 7). The temperature-dependence of the heat capacities is neglected for this work. We confirmed that this is a valid assumption, as explained further in the results and the supporting information (section S.13).
