The nonlinear effects in rotational spectra of molecules and atomic nuclei caused by the centrifigual and Coriolis forces are considered. As the angular momentum of the system increases, qualitative changes of rotational motion may occur due to the appearance or disappearance of a dengeneracy. This critical phenomenon corresponds to the bifurcation in classical mevchanics. The different types of the bifuractions experiemntally observed in molecular and nuclear spectra are discussed.
