We conclude that all gases possess a minimum molar heat capacity of due to the translational degrees of freedom of their constituent molecules. The electronic degrees of freedom of gas molecules ( i.e. , the possible configurations of electrons orbiting the atomic nuclei) typically give rise to absorption and emission in the ultraviolet or visible regions of the spectrum.
