Abstract
The rovibrational dynamics of a highly excited asymmetric triatomic mo lecule have been investigated using semiclassical and quantum mechanic al methods. The rotational energy surface (RES) has been calculated ex actly from the rigid-bender model of the molecule. The RES topology ha s been studied and the bifurcation of its critical points has been fou nd at a certain critical value of the angular momentum. A reorganizati on of the energy level structure, due to a change of the RES topology, has been revealed.
