Q2: The electronic configuration for doubly excited benzene is (azu)? (215)? (C2u)2. De- termine the symmetries (including multiplicities) for all the states associated with this configuration. (10 pts) Q3: Two NO2 molecules having C2v symmetry can form an N-N bond to yield N204 which has four equivalent oxygen atoms. Assume that N2O4 is planar and determine: (20 pts) the number of infrared active fundamentals. the number of Raman active fundamentals. the number of infrared lines expected to coincide in frequency with Raman lines
