A regularity is found for the anomalous behavior of the rotational and centrifugal distortion parameters of the water molecule in the bending states (0v20). This regularity is described by simple nonpolynomial formulae which are used to calculate Watson's parameters A, ΔK, ΔKJ, δK, HK, HKJ, hK, LK, LKKJ, and lK for the states (010), (020), (030), and (040). The calculated v2 behavior of these parameters is in agreement with the experimental one.
