Table S.4: Experimental and calculated ionization energies (in kcal mol-1) for the G3/05 test set for compounds containing elements of the first and second period of the periodic table. G3X, G3X-CEP, G3X(CCSD)-CEP, EnAt1 and EnAt2 are the differences between the experimental data and the G3X, G3X-CEP, G3X(CCSD)-CEP, G3X-CEP+EnAt1 and G3X(CCSD)-CEP+EnAt2 calculations, respectively. 47

Table S.5: Experimental and calculated electron affinities (in kcal mol-1) for the G3/05 test set for compounds containing elements of the first and second period of the periodic table. G3X, G3X-CEP, G3X(CCSD)-CEP, EnAt1 and EnAt2 are the differences between the experimental data and the G3X, G3X-CEP, G3X(CCSD)-CEP, G3X-CEP+EnAt1 and G3X(CCSD)-CEP+EnAt2 calculations, respectively. 49

Table S.6: Experimental and calculated proton affinities (in kcal mol-1) for the G3/05 test set. G3X, G3X-CEP, G3X(CCSD)-CEP, EnAt1 and EnAt2 are the differences between the experimental data and the G3X, G3X-CEP, G3X(CCSD)-CEP, G3X-CEP+EnAt1 and G3X(CCSD)-CEP+EnAt2 calculations, respectively. 50

Table S.7: Experimental and calculated atomization energy (D0) for the G3/05 test set (data in kcal mol-1) for molecules containing non-transition third-row elements. G3X, G3X-CEP, G3X(CCSD)-CEP, EnAt1 and EnAt2 are the differences between the experimental data and the G3X, G3X-CEP, G3X(CCSD)-CEP, G3X-CEP+EnAt1 and G3X(CCSD)-CEP+EnAt2 calculations, respectively. 50
