Short summary
Magic-angle-spinning nuclear magnetic resonance (NMR) is ideal for studying protein structure and dynamics. Introducing fluorine atoms offers advantages due to the NMR properties of 19F and the absence of natural fluorine. However, the slow spin polarisation recovery of 19F causes long recycle delays between scans. We demonstrate that adding paramagnetic co-solutes to solid protein samples largely accelerates these experiments, and we identify optimal conditions for this approach.
