The equilibrium geometries of the acids H3BO3, H2CO3, HNO2, HNO3, HPO3, HClO4, H2SO4, CH3SO3H, CF3SO3H, FSO3H, ClSO3H, H2SeO4, H3PO4. HCO2H, HCOOOH and C6H5CO2H, and of the anions H2BO3-, HBO32-, BO33-, HCO3-, HSO4-, CH3SO3-, CF3SO3-, FSO3-, ClSO3-, HSeO4 , HPO42-, H2PO4-, PO43-, HCO2-, HCOOO- and C6H5CO2- were determined at the self-consistent field (SCF) level, employing polarized split-valence basis sets. The MP2/6-31G** level was adopted to optimize the geometries of H3BO3, HBO2, H2CO3, HNO3, HPO3, HNO2, HCO2H and HCOOOH; those of the anions H2BO3-, HBO32-, HCO3-, HCO2- and HCOOO- were studied at the MP2/6-31G** level. The last section of the study reports the results of SCF calculations on the hydrogen-bonded complexes (HCO2-) (H2O), (CO32-) (H2O) and (HCO3-) (H2O).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
