Representation Products:

⊗	A1	A2	E
A1	A1	A2	E
A2	A2	A1	E
E	E	E	A1+A2+E

Transition Products:

For the D₃ point group, the irreducible representation of the dipole operator is A₂+E. Transitions that are dipole forbidden are indicated by parentheses.

⊗(A2+E)⊗	A1	A2	E
A1	(A2+E)	A1+E	A1+A2+2E
A2	A1+E	(A2+E)	A1+A2+2E
E	A1+A2+2E	A1+A2+2E	2A1+2A2+4E
