2. The diagram below shows the molar extinction coefficients for the absorbances in the UV/vis spectrum for \( \left[\mathrm{PtI}_{6}\right]^{4-} \). (a) Identify the term symbol for the electronic ground state of the complex. (2 marks) (b) State the number of spin allowed d-d electronic transitions that you would expect to observe in the UV/vis spectrum and why. (2 marks) (c) Suggest the origin of the other peaks observed in the spectrum (4 marks)
