Solution

If the relevant ground manifolds have electronic degeneracies $g_A$, $g_B$ and $g_{\rm TS}$, and their components are treated as energetically degenerate, multiply the result by
$$
\boxed{\frac{g_{\rm TS}}{g_Ag_B}}.
$$
Only reactive transition-state electronic channels should be counted. Resolved electronic splittings require <electronic partition functions> rather than simple integer degeneracies.
