[Pw_forum] t2g eg

[Matteo Cococcioni]

Dear Sakhraoui,

eg and t2g are the two groups of states that form when d states split
in a cubic crystal field. you can find this explained in many
condensed matter text books and even a more complete collection of
cases in chemistry text books where ligand field theory is
illustrated.
