Question

Hello, can you help me with any of these questions please? Any help would be much appreciated.

Using diagrams indicate the symmetry elements present for each of the two isomers cis- and trans-[Mo(CO)(L)2] (IV and V). Assign the point groups of IV and V. Taking the four CO triple bonds of the carbonyl ligands (Si -S4) as your basis set, work out the reducible representation spanned by these bonds for the cis isomer V, below. IK OEC O SE Using the reduction formula determine the irreducible representations spanned by this basis set (your answer should be of the form nA, + mA2 +... where n and m are integers) A diagrammatic representation of these modes of vibration is set out below. For each mode of vibration, assign which irreducible representation it transforms as.
