An analysis of the precession of the rotational oscillations of water molecules is made using the model of a two-frequency pendulum in the entire range of its oscillations. It is found that the precession of a two-frequency pendulum in the field of inhomogeneous interaction forces is anisotropic. The largest anisotropy is observed at the critical point of the change in the type of oscillations from the two-frequency one to the single-frequency one. The manifestation of precession singularities (phase changes) in the region of two-frequency oscillations, observed for cases of small initial velocities of pendulum oscillations, is considered
