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