Potential curves for the lower unbound Hg2(X0g+) state and the upper Hg2(D1u) state of the mercury dimer are determined by multiply repeating calculations of the desired spectrum and comparing the results obtained with the experimental data. Initial Morse potentials are supplied with patches, making the potentials steeper on one of its wings and more flattened on the other wing compared to the usual Morse potential. The values of ωe and ωexe for the Hg2(X0g+) and Hg2(D1u) states are determined according to several lowest vibrational states of the terms. Coordinates of turning points are also given for the corresponding states. These data seem to be useful in studying the mercury dimer by the traditional method with a low vibrational excitation.
