In previous reports, the information contained in the cumbersome five spherical harmonics parameters was translated to the so-called model-free (MF) parameters, which are more intuitive and can easily be related to a starting structure. These MF parameters are the order parameter, the amplitude (ηrdc) and direction (ϕ′rdc) of motional anisotropy and the average orientation polar angles (ϕav,θav), and are obtained according to transformations derived in (Lakomek et al. 2006, 2008a).3 4 5 6"}
