The 19F-13C TROSY principle opens exciting opportunities to probe structure, dynamics and interactions in large biomolecular systems, in which the 19F-labels can be incorporated either into a protein or a nucleic acid residue. The fluorine atom is an extremely sensitive probe towards its chemical environment thanks to high CSA (chemical shift anisotropy), at the same time CSA also badly broadens the NMR-signals of 19F-labels in biomacromolecules. The so called TROSY effect can be used to combat CSA and narrow the linewidth of the 19F-signals allowing their detection by solution state high-resolution NMR spectroscopy.
