Do rotational degrees of freedom contribute to temperature?

The internal energy resides partly in the motions of the molecules and partly in the vibrations of atoms within the molecules.
When you measure the temperature you are measuring the motions of the molecules.
If a high proportion of the energy is in motions within molecules then you will need to raise the internal energy more for the same measured rise in temperature.

I did, and my previous reply paraphrases what the book says.
