Dependencies of a longitudinal ¹⁵N relaxation rates R₁, b transverse relaxation, R₂, c ¹H–¹⁵N dipolar order parameters, given as the ratio of measured and rigid-limit dipolar coupling, and d ¹H–¹⁵N dipole-¹⁵N CSA cross-correlated relaxation rate constants on the amplitude and time scale of motion in the framework of the simple model-free description
