WebThe wavefunction has an internal instability. From the additional data given by the stability analysis it appears that the triplet state optimized with the default guess does NOT converge to the triplet state of correct symmetry (and lowest energy). http://archive.ambermd.org/202403/0112.html#:~:text=The%20wavefunction%20IS%20NOT%20YET%20CONVERGED%21%20It%20shows,can%20be%20used%20as%20input%20for%20another%20calculation.

"WebJun 15, 2016 · There is no physical requirement for a wave function to be smooth, or even continuous. At least if we accept the common interpretation that a wavefunction is nothing else than a "probability amplitude". I.e. it represents, when multiplied with its complex conjugate, a probability density. " - Orca this wavefunction is not fully converged
