8) For the molecule below, draw all 4 possible CO vibrations. Give each vibration a symmetry label and indicate whether the vibration would be visible in IR and/or Raman spectroscopy. Hint: The different CO ligands vibrate as a group and the axial vibrations should be considered together as one group while the movements of the equatorial CO ligands should be considered as a separate group.
