In polyatomic molecules, the Wigner-van Neumann non-crossmg rule is generally relaxed because of the cxistcncc of more than a single nuclear coordinate. Potential energy surfaces may or may not intersect. There is an interesting class of states where an intersection cannot occur if only the dominant
