Short summary
NMR represents a key spectroscopic technique for studying intrinsically disordered proteins (IDPs) that lack a stable three-dimensional structure. We present a set of NMR experiments tailored for proline residues, which are highly abundant in IDPs. The novel experiments have very interesting properties for the investigation of IDPs of increasing complexity.
