Using a basis set of atomic natural orbitals of valence triple-zeta plus double polarization quality, the core-electron binding energies (CEBEs) ofHF, H20, N2 and CO were computed by the deMon density-functional program with a combined functional of Becke's exchange (B88 ) with Perdew's correlation
For each of the X Λ3B 1 , a Λ1A 1 , and b Λ1B 1 electronic states of the BH 0 2 molecular ion we have calculated over 50 ab initio points on the potential energy surfaces using the MRD-CI method for all eight electrons. Analytical functions were fitted through the points for each state, and the func
