- Long-range_potential abstract "Due to the simplicity of the Morse potential (it only has three adjustable parameters), it is not used in modern spectroscopy. The MLR (Morse/Long-range) potential is a modern version of the Morse potential which has the correct theoretical long-range form of the potential naturally built into it. It was first introduced by professor Robert J. Le Roy of University of Waterloo, professor Nikesh S. Dattani of Oxford University and professor John A. Coxon of Dalhousie University in 2009 and since then it has been an important tool for spectroscopists to represent experimental data, verify measurements, and make predictions. It is particularly renowned for its extrapolation capability when data for certain regions of the potential are missing, its ability to predict energies with accuracy often better than the most sophisticated ab initio techniques, and its ability to determine precise empirical values for physical parameters such as the dissociation energy, equilibrium bond length, and long-range constants. Cases of particular note include: the c-state of Li2: where the MLR potential was successfully able to bridge a gap of more than 5000 cm−1 in experimental data. Two years later it was found that Dattani's MLR potential was able to successfully predict the energies in the middle of this gap, correctly within about 1 cm−1. The accuracy of these predictions was much better than the most sophisticated ab initio techniques at the time. the A-state of Li2: where Le Roy et al. constructed an MLR potential which determined the C3 value for atomic lithium to a higher-precision than any previously measured atomic oscillator strength. This lithium oscillator strength is related to the radiative lifetime of atomic lithium and is used as a benchmark for atomic clocks and measurements of fundamental constants. It has been said that this work by Le Roy et al. was a "landmark in diatomic spectral analysis". the a-state of KLi: where an analytic global (MLR) potential was successfully built despite there only being a small amount of data near the top of the potential.The MLR potential has successfully summarized all experimental spectroscopic data (and/or virial data) for a number of diatomic molecules, including: N2, Ca2, KLi, MgH, several electronic states of Li2, Cs2, Sr2, ArXe, LiCa, LiNa, Br2, Mg2, HF, HCl, HBr, HI, and MgD.".
