 Dear All,
 By surveying on "Interaction Enthalpy" of transition metal complex in
 vacuum and solvent (PCM or other model), I found in all cases that the enthalpy
 change in vacuum is larger than that solvent. For example, if delta H in vacuum=
 -1000 kcal/mol, in solvent= -200 kcal/mol. Could anyone explain why?
