Thus, it is natural to search for an approximated solution of the non-degenerated problem with the same functional form. On the other hand, for a given E, there are many more microstates involving changes in the number of quanta in the low-frequency than in the high-frequency modes. Thus, it may be helpful to weigh the average frequency toward the low-frequency modes. If we take as weight the maximum number of quanta we can add to a specific vibrational mode, max / kk n E h = corresponding to the microstate ( )
