摘要: Density functional theory and the unrestricted generalized transition state (uGTS) model were applied to study the
core-electron binding energies (CEBEs) of open-shell molecules. Basis set scaling based on Clementi and Raimondi's rules for atomic screening was used along with the cc-pVTZ basis set. The scaled pVTZ basis set is almost as good as the
cc-pVSZ and complete basis set limit in predicting CEBEs. For small molecules (O:,, NO, NF2 and NO2) the average
absolute deviation (aad) of our prediction (scaled pVTZ) is only 0.29 eV. For the larger molecule (CF3)2NO the aad is
0.56 eV, compared with experimental uncertainty of 0.5 eV. Theoretical predicted multiplet splittings for the small molecules agree quite well with experiment: the average deviation is -0.33 eV. For (CF3)2NO the calculated multiplet splittings are much smaller than the experimental ones. We also predict the CEBEs of PO, SN and SO, whictl have not been observed experimentally.
