✦ Synopsis
The use of state-average MCSCF energy functionals in molecular calculations can give rise to specific bistabilities of solutions and therefore to discontinuities of computed potential surfaces. We present a model analysis of this phenomenon and consider a numerical example concerning ab initio CASSCF calculations on the two lowest 'Z+ states of the ScH molecule.
