| Sep 29, 2017 at 8:03 | comment | added | John Rennie | @HernanMiraola: the temperature is related to the energy in the internal degrees of freedom by the equipartition theorem. As long as you have enough internal degrees of freedom to be statistically significant you can assign a temperature just by looking at the rotational and vibrational modes of the molecule. | |
