Notes:
Study of the relaxation of vibrational energy in a polyatomic fluid is usually based on a simple definition of the vibrational energy as the sum of the energies of the internal degrees of freedom of the molecules. Extensive computer simulations have shown that this is not in fact the best variable to use in a hydrodynamic theory because it is not the most slowly relaxing variable. We propose an alternative definition (omitting very hot vibrators) which relaxes much more slowly, and is therefore more useful on a hydrodynamic time scale.
