- Assume that x- polarized light can be assigned an E symmetry species in a system that has C4v symmetry. Can a transition from E state to a B2 state occur? Why or why not?The mutual exclusion rule states that for certain molecules, vibrations that are IR-active are not Raman-active, and vice versa. Molecules must have a certain symmetry element in order for the mutual exclusion rule to apply. Examine the character tables in Appendix 3 and determine what that symmetry element is.Identify the point group of the wave functions of the following molecules. a Deuterium oxide, D2O where D=2H b Boron trichloride, BCl3 c Phosphorous trichloride, PCl3
- What is the term symbol for the ground state of a Li, b Al,c Sc?Spin orbitals are products of spatial and spin wavefunctions, but correct antisymmetric forms of wavefunctions for multielectron atoms are sums and differences of spatial wavefunctions. Explain why acceptable antisymmetric wavefunctions are sums and differences that is, combinations instead of products of spatial wavefunctions.Use group-theoretical arguments to determine the term symbols for B2, which has two unpaired electrons in doubly degenerate u molecular orbitals.

If the electronic ground state of methane has A1g symmetry and x- polarized light has the label T2, what are the symmetry labels of allowed excited electronic states? Use the Td character table in Appendix 3.The Cu(H2O)62+ complex has octahedral symmetry.
