Empirical group shifts for estimate of the core electron binding energies of compounds of 14 elements are evaluated. It is shown, for elements of the first row of the periodic table, that simple one-parameter groups shifts are inadequate for estimating core binding energies of highly positively charged atoms with polarizable ligands. In the case of carbon 1s binding energies, a method involving two parameters - an electronegativity parameter and a polarizability parameter - is devised which significantly improves the accuracy of the predictions. The nitrogen 1s binding energies of the aminoboranes, NH/sub 2/BH/sub 2/, N(CH/sub 3/)/sub 2/BF/sub 2/, NH(CH/sub 3/)BF/sub 2/, and NH/sub 2/BF/sub 2/, are estimated. These data, when combined with the nitrogen p..pi.. ionization potentials, lead to the conclusion that there is an important degree of N-B ..pi.. bonding in all of these molecules.
