I know how to calculate qv = 1/(1-e^-hv/kt)

but if the question state the following

The real vibrational frequencies in the activated state are 2300 cm-1 and 400 cm-1 doubly degenerate

How do i treat it when its doubly degenerate?

There's a degeneracy coefficient in the partition coefficient expression.

See about 1/3 of the way down the page, coefficient g_j.
