Question
a. What is the point group for NH3?
b. Copy the Character Table for the identified point group here (this must be correct;
otherwise, the rest of the work will be wrong)
c. For the central N atom, the symmetries for 2s and 2p can be read directly from the
Character Table:
(1) What is the symmetry (Mulliken symbol) for 2s?
(2) What are the symmetries (Mulliken symbols) for 2px, 2py and 2pz?
d. For 3 H atoms, we can treat three 1s orbitals as a group.
(1) What are the reducible representations?
(2) Reduce the reducible representations to irreducible representations
