1. Use a group theoretical approach to propose a molecular orbital scheme for the electron network of trimethylenemethane. Trimethylenemethane has a planar, D3 3h, structure. H₂C =CH₂ a. Using the three 2p, orbitals on the terminal C atoms as a basis, generate a reducible representation. Note that the z-axis is perpendicular to the plane of the page. Reduce this representation to its component irreducible representations. You should end up H₂C with one non-degenerate irreducible representation and one doubly degenerate irreducible representation. - b. Use projection operators to project out the appropriate linear combinations of the basis orbitals to make reasonable SALCs. To obtain the non-degenerate SALC, use the projection operator on Q₁. For the doubly degenerate pair, one SALC can be obtained by using the appropriate projection operator on ₁. The second can be obtained by using the appropriate projection operator on (9₂ 93). Sketch the resulting SALCs. c. Sketch the four molecular…
The photoelectron spectrum of HBr has two main groups of peaks. The first has ionization energy 11.88 eV. The next peak has ionization energy 15.2 eV, and it is followed by a long progression of peaks with higher ionization energies. Identify the molecular orbitals corresponding to these two groups of peaks.
Following the pattern of Figure 6.21, work out the correlation diagram for the BeN molecule, showing the relative energy levels of the atoms and the bonding and antibonding orbitals of the molecule.

The highest occupied molecular orbital of a molecule isabbreviated as the HOMO. The lowest unoccupied molecularorbital in a molecule is called the LUMO. Experimentally,one can measure the difference in energy betweenthe HOMO and LUMO by taking the electronic absorption(UV-visible) spectrum of the molecule. Peaks in theelectronic absorption spectrum can be labeled as p2p9p2p*,s2s9s2s*, and so on, corresponding to electrons being promotedfrom one orbital to another. The HOMO-LUMO transitioncorresponds to molecules going from their groundstate to their first excited state. (a) Write out the molecularorbital valence electron configurations for the ground stateand first excited state for N2. (b) Is N2 paramagnetic or diamagneticin its first excited state? (c) The electronic absorptionspectrum of the N2 molecule has the lowest energypeak at 170 nm. To what orbital transition does this correspond?(d) Calculate the energy of the HOMO-LUMO transitionin part (a) in terms of kJ/mol. (e) Is the…
