2. (4 pts) For a coordination complex withCav symmetry and a ground state in which all of the electrons are paired, will a transition to an excited state in which an electron has been excited from a b, orbital into a b, orbital be allowed or forbidden? If it is allowed, what is its polarization? Make sure to indicate the symmetries of the ground and excited states.
