1. The problem statement, all variables and given/known data I am wondering how for determine the central atom's orbitals from the point group character tables described by group theory. For example CO3^-2 (D3h) Carbon's (central atom) p-orbitals are described by a1''+e'. The s-orbital is a1' 2. Relevant equations 3. The attempt at a solution I'm not entirely sure how this was obtained. I'm certain that they are found from just reading the right side of the character table but I am unable to find any resources describing it any further.
