The "crossover" of the energy spectrum of a molecule during rotational excitation corresponds to a series of bifurcations in the classical limiting problem. The sequence and type of these bifurcations are determined by the symmetry conditions. This effect is studied in the high-resolution spectrum of R 3_ band of the v3 state of the CF4 molecule.
