I think that the current definition of Boltzmann distribution is misleading. The probability of a microsate, say , is . but a given energy can be degenerate, so I think that it should be written something like
![{\displaystyle \propto \exp \left[-E(X_{i})\right]}](https://wikimedia.org/api/rest_v1/media/math/render/svg/2723c183e143d7747e97d16ab6b4a7bba6fd6023)
- ,
![{\displaystyle f(E)\propto \Omega (E)\exp \left[-E/k_{B}T\right]}](https://wikimedia.org/api/rest_v1/media/math/render/svg/725f1e2b5447a4afad931d9e8e7df8b9f9de382f)
where is the degeneracy of the energy ; therefore
- .
![{\displaystyle f(E)={\frac {1}{Z}}\Omega (E)\exp \left[-E/k_{B}T\right]}](https://wikimedia.org/api/rest_v1/media/math/render/svg/29989eb0fa666f3d8a3535c8e19c64d4ed203c45)
