a. Assign the point groups for A and B assuming the M-C bond distances are the same and that the C-N bond distances are the same. Also, all C-M-C bond angles for nearest neighbor cyanide ligands are 90°. b. Determine the irreducible representations for the C-N stretching vibrations in A and B (you will first need to find the reducible for these modes and then reduce that representation). c. Identify the number of IR and Raman active modes for A and B. d. State and explain whether one can distinguish between the two possible geometries using only IR spectroscopy.

By using the given 1) electronic absorption spectrum, 2) the Tanabo-Sugano diagram for d3 complex in octahedral ligand field and 3) the absorption/emission spectra, explain the following: a) Ligand field states (to support your explanation show the filling of the orbitals) b) Radiative transitions (to support your explanation refer to fluorescence, phosphorescence and Stokes’ shift)
The crystal structure of the potassium salt of PtH42 has been recently determined (Bronger et al, J. of Less Common Metals, 116:9-15, 2012). The ion adopts a square planar structure and belongs to the D4h point group. Using the Projection Operator method, the ligand group orbitals (LGO) has been determined to have the following symmetry: A13+ B1g + Ej. Using the D4h Character Table, determine which d orbital of the central Pt atom have the right symmetry to interact with the A1g and B1, Ligand Group Orbitals (LGO).

1. The molecule listed to the left was originally MX6 where the symmetry was On. After reduction of the metal center the coordination environment changed and the ligands along the Z-axis elongated(hint: this means that the extent of overlap of orbitals that interact with the z-axis point charges would be lesser than the On molecule). Draw the crystal field splitting of both the On symmetry molecule as well as elongated z-axis molecule with symmetry labels.
1. Below are two views of the triflate anion, CF3SO3−. a. Using the conventions learned in class, draw the following: i. A cartesian coordinate system. Indicate which view your coordinate system corresponds to. ii. The principal axis of rotation. Give the axis using the proper notation for symmetry elements. iii. One of the mirror planes. Name the mirror axis, including the name of the cartesian plane. b. List ALL unique symmetry operations present for triflate. You do not need to include redundant ones (e.g. since, C33 = E, you do not need to include C33). c. What is the point group of triflate?
