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...
