I'm still struggling with visualizing.

Say, if I wanted to find the Reducible Representation for a T-shaped molecule, like ClH₃ or ClF₃ and I "approximate" it with C_2v symmetry. What would be its reducible representation (for sigma bonds and maybe pi bonds in the p_y orbital)?

I find it hard to see the C₂ axis, but my "guess" is 3 1 3 1, which would get me 2A₁ + B₁. For the pi bonds in p_y, I think it's doubled that.

Ideas?
