4.12 Below is shown the Schlegel diagram for the C
24
fullerene. It is a cage struc-
ture with hexagonal faces at top and bottom, capping a crown of twelve pen-
tagons around its waist. The valence shell of this structure is formed by a set
of 24 radial
p
σ
-orbitals, one on each carbon. Determine the point group of this
molecule and the irreps describing the valence shell. (Hint: divide the set of
24 orbitals into two separate orbits.)
