# Polarisation orbitals are potentially problematic for Groups I and II.
|
|
# The highest energy valence orbital is l=0 so the polarisation orbital
|
|
# using the standard perturbative approach would be l=1, but that would
|
|
# mean a basis set with only l=0 and l=1. It is also possible to polarise
|
|
# perturbatively from the highest energy l=1 orbital to give a polarisation
|
|
# orbital with l=2 using the lines below, but this will be perturbing a
|
|
# semi-core state and will give a basis where the only l=1 orbitals are
|
|
# semi-core states. This may not be reliable: we recommend careful testing
|
|
# should you choose this route.
