Question

Question: Apply the reduction formula to identify the irreducible representations spanned by the four CO bonds in IV and V. Show your working.

I have attached the reducible formula along with structures for IV and V

Please help. Thank you.

The reduction formula The reduction formula gives us a "handle turning" procedure for reducing the representation spanned by a set of basis functions. The formula looks abstract and somewhat impenetrable when first encountered, but is actually quite simple to use in practice. n(i) = {x,(?)X,(?) n(i) = Number of times the ith irreducible representation occurs in the representation r that we are aiming to reduce. h = Order of group i.e. the number of operations in the group (this is not always the same as the number of classes of operations). = This denotes a summation over all the operations R in the group. If there is more than one operation in a given class we must remember to include each operation in the summation X(R) = Character of the reducible representation r under the symmetry operation R. (R) = Character of the irreducible representation i under the symmetry operation R.
