Eigenvalues of the normal modes as a function of for . The axial mode frequencies (blue circles) decrease and planar mode frequencies (red triangles) increase as increases, as shown in the four cases illustrated: (a) , (b) , (c) and and (d) . For (b)-(d) the eigenvalues of the normal modes also are closer together at low and separate as increases. The axial frequencies have two degeneracies and the planar frequencies have four degeneracies as discussed in the main text.
