Part B
Cetermine the SALCS for all of the sulfur s- and p-orbitals. For full
credit, derive the irreducible representations, draw and write the expression for the sulfur
SALCS. Use additional pages if needed.
Part C
Sketch a Molecular Orbital Diagram for CS2 based on the SALCS
generated in part B. Fill the diagram with the appropriate number of electrons and draw
all bonding, non-bonding and anti-bonding molecular orbitals. Also indicate the
symmetry of each molecular orbital. Be sure to draw pictures of the molecular orbitals
(i.e. AO's + SALCS) to accompany their placement in the diagram.
