I'm working through a molecular symmetry textbook and something keeps nagging at me. If I derive the SALC-AOs for NH3 (using the projection operator method), I'll get
A1: $ \frac{1}{\sqrt{3}}(\phi_1+\phi_2+\phi_3)$
Doubly-degenerate E:
$ \frac{1}{\sqrt{6}}(2\phi_1-\phi_2-\phi_3)$
$ \frac{1}{\sqrt{2}}(\phi_2-\phi_3)$
where the $\phi$s are the H 1s orbitals, ie.:
(This was the best image I could find, but in the second E orbital the black s-orbital should be enlarged)
I'm having trouble seeing how these SALC-AOs would be a member of their symmetry species. The A1 SALC-AO is identical under each operation, so it makes sense that it would belong to A1. But if I want to confirm that the two E SALC-AOs belong to E, how would I do that?
My intuition is that I should be able to apply each C3v operation to the SALC-AO and get back the E row of the character table (Below). But if you apply a C3 rotation to the e2 orbital, you get the black orbital taking the place of the white orbital, the white taking the place of the node, and the node taking the place of the black orbital. This doesn't seem like it could be expressed as a number in a character table, since the SALC-AO isn't being taken to itself or -itself.
Am I thinking about this all wrong? How should I understand the SALC-AO as a whole? Any guidance is appreciated, the textbook seems evasive on this.
