What is it about?
This research paper discusses the Tietz potential and its applications in studying diatomic molecules. A formula is derived to relate the four parameters of the Tietz potential, and it is applied to five different molecules. The equilibrium bond length of Tietz potential varies with temperature and the type of molecule, with the largest value found in scandium iodine and the lowest in carbon monoxide.

Why is it important?
A formula has been derived to relate the four parameters of Tietz potential using principles of statistical mechanics. The formula shows that the equilibrium bond length of Tietz potential varies slowly with absolute temperature and linearly with the radius of the particles. The formula has been applied to five different molecules, showing that the equilibrium bond length of Tietz potential varies from 1 to 5 Å and is largest for scandium iodine and lowest for carbon monoxide.
Perspectives
Tietz potential has multiple forms and four parameters for spectroscopic fitting.
