Degeneracy of vibrational energy levels
WebHowever, noting that whenever there is degeneracy, sum of the terms in the sum will be the same, we can rewrite the partition function as a sum over levels \begin{align} Z = \sum_{n} g_n e^{-\beta E_n} \end{align} The degeneracy factor is precisely what counts the number of terms in the sum that have the same energy. WebThe first excited vibrational energy level of ditomic chlorine (Cl 2) is 558 cm −1 above the ground state. Wavenumbers, the units in which vibrational frequencies are usually recorded, are effectively units of energy, with 1 cm −1 =1.986445×10 −23 J. If every vibrational energy level is equally spaced, and has a degeneracy of 1, sum over the …
