Preferred Label : surface crossing;
IUPAC definition : In a diagram of electronic energy versus molecular geometry, the electronic energies
of two states of different symmetry may be equal at certain geometrical parameters.
At this point (unidimensional representation), line or surface (more than one dimension),
the two potential-energy surfaces are said to cross one another.;
