locking the desired MO configuration

Dear developers;

I would like to perform an optimization on the
locked orbital configuration and I am not sure
whether I can do it or not. The principle story is
simple; imagine there is a three fold degenerate
state of Tg (No.;50,51,52) and we have two
situations (by adding 3 electrons to this state);

Low spin === 50(up-dn), 51(up)
High spin == 50(up),51(up),52(up)

The question is a low spin state with the higher
energy than previous one. This spin state, can be
called spin-flip state;

LS(spin flip)===50(up),51(dn),52(up)

I would like to do it within DFT, by fixing
configuration of orbital. In principle it should
be possible.

I would be grateful, if somebody give a hint to me.


Best regards,

Shahab
