Webk is Boltzmann’s constant. Population inversion will happen if the no of atom in excited state N2 is higher than the no of atom in ground state i.e. N1. From the equation we can say that the ratio of N2/N1 is greater than 1 only when the thermodynamic temperature T is negative as E2 – E1 will always be positive. WebAs a function of energy and temperature, Boltzmann's Equation shows how the atoms will be distributed across the various energy levels. The below given is the Boltzmann …
The corresponding ratio of populations of energy levels must also take their degeneracies into account.
