Question

Ν. Ο 1. T-electron reducible representation. Deduce reducible representation for the t-electrons and break down into irreducible components. 2. Normal vibrations. Deduce reducible representation for the normal vibrations of the molecule in its ground state and break down into irreducible components. 3. IR and Raman spectroscopy. Deduce the electric dipole IR spectral selection rules for the normal vibrations (ground state), and also the Raman spectrum selection rules 4. Electronic spectroscopy. Classify n-orbitals by symmetry species of Don and deduce the possible r -> * electronic excitations. Deduce the electric dipole and electric quadruple selection rules for the above transitions. 5. Vibrational pertubation. For any electric dipole forbidden electronic transition in 4, show if any of the normal vibrations found in 2 can act as a vibrational pertubation to make the transition electric dipole allowed. Do similar processes to find the possibly allowed transitions by SO (spin-orbit) pertubation.
