| Abstract: | A universal analytic potential energy function is derived using the cosine function with a phase factor,which is suitable to be applied to the interactions between two atoms in a molecule or molecule and ion.5 kinds of common potential curves are obtained by adjusting phase factors.The spectroscopic constants of 20 kinds of molecule are calculated by using the potential energy function,and all the calculation results are in good agreement with experimental data. |
| Keywords: | universal potential energy function force constant spectroscopic constant |
