## Abstract The half‐projected Hartree–Fock function for singlet states (HPHF) is analysed in terms of natural electronic configurations. For this purpose the HPHF spinless density matrix and its natural orbitals are first deduced. It is found that the HPHF function does not contain any contributi
## Abstract Unrestricted Hartree–Fock (UHF) SCF–MO calculations on the doublet reaction surface for the addition of methylidyne (CH) to ethylene (C~2~H~4~) using the standard extrapolation techniques of the GAUSSIAN 70 program show erratic behavior. On the other hand, the potential energy surface c
The geometry and vibrational spectrum of TeCl was calculated with 4 w Ž . various quantum chemical methods Hartree᎐Fock, second-order Møller-Plesset MP2 Ž . x and generalized gradient approximation density functional theory GGA-DFT . Five different basis-set combinations were tested: the relativisti
The present study examines the feasibility of combining the correlation-consistent basis sets developed by Dunning and coworkers with the hybrid Hartree᎐Fockrdensity functional method B3LYP. Furthermore, Ž . extrapolation to the complete basis set CBS limit minimizes errors due to the presence of an
