In this work exponentially fitted Runge‐Kutta‐Nyström methods which integrate exactly the test equation yn = −w2y. We modify existing fifth and sixth order methods and apply the new methods on the computation of the eigenvalues of the Schrödinger Equation with different potentials as the harmonic oscillator, the doubly anharmonic oscillator and the exponential potential.
