#
# - [``idealgas``](https://vlachosgroup.github.io/pMuTT/statmech.html#ideal-gas-idealgas) - Ideal gases
# - [``harmonic``](https://vlachosgroup.github.io/pMuTT/statmech.html#harmonic-approximation-harmonic) - Typical for surface species
# - [``electronic``](https://vlachosgroup.github.io/pMuTT/statmech.html#electronic-electronic) - Only has electronic modes
# - [``placeholder``](https://vlachosgroup.github.io/pMuTT/statmech.html#placeholder-placeholder) - No contribution to any property
# - [``constant``](https://vlachosgroup.github.io/pMuTT/statmech.html#constant-constant) - Use arbitrary constants to thermodynamic properties
