Problem: Consider the planar urea molecule. i) Determine the point Group, as well as the symmetry of the x,y and z coordinates. ii) Consider the following atomic orbitals: C : 2s; 2p N : 2s; 2p O : 2s; 2p H : 1s Determine the equivalent sets of orbitals and the symmetry of each set. Solution: i) Found the pointgroup to be Cs, and symmetry x,y = A' and z = A''. Don't know how to tell which ones are equivalent and which symmetries they have. Can someone please help?
