The suitability of the pair condensate approach for rotational states is studied in a single j =shell of identical nucleons interacting through a quadrupole-quadrupole Hamiltonian. The ground band and a K =2 excited band are both studied in detail. A direct comparison of the exact states with those constituting the SD and SDG subspaces is used to identify the important degrees of freedom for these levels. The range of pairs necessary for a good description is found to be highly state dependent; S and D pairs are the major constituents of the low-spin ground-band levels, while G pairs are needed for those in the y band. Energy spectra are obtained for each truncated subspace.SDG pairs allow accurate reproduction of the binding energy and E =2 excitation energy, but still give a moment of inertia which is about 30% too small even for the lowest levels.
