### Degeneracy

Can someone explain to me the concept of degeneracy (W) and how to calculate it.

### Re: Degeneracy

Degeneracy means if it corresponds with two or more states of a quantum system that are measurable

### Re: Degeneracy

Degenerate describes states that have the same energy level, but different positions/configurations. For example, the three p-orbitals of a given energy level are degenerate. Calculating it is complicated because it depends on the number of particles and the types of particles in the system.

Does anyone know the context in which we would have to be able to solve this?

### Re: Degeneracy

I think the problem he did in his lecture was a good example. You have to identify the number of orientations the molecule can be in. Lets say its 3. Then you raise this number to the power of how many molecules of it there are. That is your W (degeneracy) in the boltzmann equation.
