## vibrational entropy

Volume: $\Delta S = nR\ln \frac{V_{2}}{V_{1}}$
Temperature: $\Delta S = nC\ln \frac{T_{2}}{T_{1}}$

### vibrational entropy

Is there a way to measure vibrational entropy? I know that residual/positional is measured through degeneracy.

### Re: vibrational entropy

I'm sure there is a way to measure vibrational entopy, since I believe depends on the temperature of the system. Vibrational entropy studies have been done on some alloys (solids), but I am not too sure how accurate measurements are.

### Re: vibrational entropy

There likely is a way to measure vibrational entropy but for the sake of this class, I think that we just need to understand this in a conceptual sense.
