Hence, the current result will still hold true for gas molecules with higher degrees of freedom; that is, the distribution of diversity is always exactly the same for an ideal gas, whether monoatomic or polyatomic.

If one simply writes, for a particular assembly of N nuclei and n electrons in a polyatomic molecule, a full hamiltonian operator that includes only terms for the kinetic energy of both electrons and nuclei with the electrostatic potential energy of all their interactions--which corresponds to the standard hamiltonian in the practice of quantum chemistry apart from an inclusion here of nuclear kinetic energy, one finds clearly that the result of the solution of the Schroedinger equation, necessarily by purely numerical means, yields only an energy, or rather prospectively a manifold of energies of all states discrete and continuous.
