For D_4h symmetry use sketches to show that d_xy orbitals have B_2g symmetry and that orbitals have B_1g ymmetry.

(Hint: you may find it useful to select a molecule that has D_4h symmetry as a reference for the operations of the D_4h oint group. Observe how the signs on the orbital lobes change as the symmetry operations are applied.)
