correct HF orbitals

[Antara Dutta]

Hello,

I've a system comprising of two atomic oxygen and one Iodine atom, they are infinitely separated at dissociation limit. Using Molpro, I did HF calc. but got wrong orbitals with Iodine (n+1)s orbitals twice and no electron in py or pz orbitals, and one of the atomic oxygen contains one extra electron in p orbitals (2p5). By rotating the orbitals, I got ionic atoms with high dipole moment value and the electron occupancy wasn't correct. How can I get correct atomic orbitals for neutral atomic dissociation limit?
Thanks

Antara
