The studies on the potential energy curves of the electronic excited states 21Πg, 43Πg, b3Πu of Na2, the states a3Σ+u, 21 Πg, B1Πu, A1Σ+u of K2 and the state 11Πg of Cs 2 molecules by using the energy consistent method (ECM) are reported here . The results show that the present ECM potentials agree very well with the know n Rydberg-Klein-Rees data or the inverted perturbation approach data, and that they are much better than other analytical potentials such as the Morse and the Huxley-Murrell-Sorbie potentials for the electronic excited states of alkali dia tomic molecules.
