Abstract | A linear regression correction (LRC) approach was developed to account for the electron correlation energy missing in Hartree-Fock (HF) calculation. This method was applied to evaluate the standard heats of formation of 180 small-sized to medium-sized organic molecules at 298.15 K. The descriptors in the LRC scheme are the number of lone-pair electrons, bonding electrons and inner layer electrons in molecules, and the number of unpaired electrons in ground state atoms. It is observed that the large systematic deviations for the calculated heat of formation are reduced drastically, in particular, for the HF results. |
