What is it about?
The improved Rosen Morse potential (IRMP) is a generalized vibrational potential used to study diatomic systems. This study found that the bond equilibrium length of the IRMP depends on temperature and particle diameter, and varies for different molecules and dimers. A formula was derived to calculate the bond length for a wide range of temperatures and molecules.

Why is it important?
The bond equilibrium length of the IRMP is one of the three independent fitting parameters and is affected by the absolute temperature and diameter of the particles in the system. The bond equilibrium length of the IRMP decreases with increasing depth of the IRMP well and increases with increasing range of the well of potential parameter. The formula for the bond equilibrium length of the IRMP can be applied to a wide range of molecules and dimers, with values ranging from 0.9 Å to 7 Å.
