But in benzene, it is still OK to think of it as pi bond and pi*(anti-bonding) states. I think the language of bonding and antibonding are are related with a representation of valence bond theory. While in molecular orbital theory, people do not talk about bonding and antibonding stuff...
I am not from chemistry either, but I did some research on bonding analysis in solid state system using a downfolding scheme called QUAMBO. So I would like to address some points as far as I know.
Hello, is there any detailed table about the s,p,d,f,etc level splitting due to various crystal symmetry(like O,Oh,D4h,...). I think it should be somewhere since it is a well established material. Can anyone help?
