Another factor that affects the transition rates is the energy of the transition ω = ω i -ω f . Ignoring the scaling involving N , all energetically favorable transitions have faster E-FGR rates than the energetically unfa- vorable transitions. On the other hand, the transient non-equilibrium rate can be many times larger than the corresponding E-FGR rates for energetically unfavorable k -→D , k D→+ , and k -→+ . This is much less pronounced for the energetically favorable k +→D , k D→-, and k +→-.
