Construction of potential curves for diatomic molecular states by the IPA method. A program package is presented which utilizes the Inverted Perturbation Approach (IPA) method for construction of potential energy curves of $^1Sigma$ and $^1Pi$ states of diatomic molecules directly from the experimental data. In most cases using the constructed IPA potential one can reproduce the experimental energy levels within the accuracy of measurement. The package is successfully tested in case of double minimum potential where the traditional RKR method is not applicable.
