The trigonal bipyramidal composite [Fe(CO)4(PMe3)] exhibits a Raman spectrum with three strong absorptions at 2051 cm-1, 1967 cm-1 and 1911 cm-1. Given that the PMe3 ligand can coordinate to either an axial or equatorial site (a) Create a reducible representation for both possibilities utilizing the C-O bond vectors only ignore the methyl groups when determining the point group. (b) Explain what are the irreducible representations of these two RRs? (c) Based on your analysis above as well as considering the experimental spectrum which of these two geometries is most likely?
