The electrons belong to the entire atom and are not constrained to any orbital. One uses orbitals to construct the wave function. One must be sure that the set of orbitals, i.e. the basis set, is sufficiently flexible to describe completely the molecular species. You are dealing with an atomic species so a polarization basis set is probably not needed.

Gday,
I would like to do an MP2 calc on a Li- species in triplet state.
With one electron in the s orbital and one in a p orbital, how can you constrain the electron to say the px orbital?
Cheers, cdth..at..unimelb.edu.au
