MO Diagram from Group Theory: Central Atom

  1. May 6, 2013 #1
    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.

    Are you having problems understanding what the Mulliken symmetry symbols "a1" or "t1" mean?
