Electronic configuration and symmetry labels of 3d$^7$ ions

These are labels for irreducible representation in the Oh point group: http://symmetry.jacobs-university.de/cgi-bin/group.cgi?group=904&option=4 T and A are standard labels for triply and singly ...

Mulliken Labels: How do I tell apart E, doubly degenerate, symmetry apart from T, triply degenerate, symmetry for a molecular orbital?

First of all — it should be noted that this is not a unique representation of the $\mathrm{e_g}$ set. You can take any two linear combinations of these two orbitals (i.e. add and subtract them), and ...

Mulliken Labels: How do I tell apart E, doubly degenerate, symmetry apart from T, triply degenerate, symmetry for a molecular orbital?

In point groups with three fold or higher axis of symmetry ($C_n$ where $n>2$) there is the possibility of degeneracy, in other words rotation about a horizontal axis and about a vertical one have ...
