We present a new determination of the potential curves and interactions of the coupled electronic states and of the potassium dimer, based on new laser spectroscopy measurements within a molecular beam, combined with data available in the literature. We used a new global deperturbation approach, involving the Fourier Grid Hamiltonian method for energy level calculation. A standard deviation of 1.2 is obtained corresponding to a variance of cm-1, representing a significant improvement compared to the standard deviation of 4 yielded by the traditional local deperturbation approach.
