Halogen Bond Strength in Solids Quantified via Zeeman-Perturbed Nuclear Quadrupole Resonance Spectroscopy Proton NMR is a ubiquitous and valuable probe of hydrogen bonds. Conversely, 127I NMR of strong halogen bond (XB) donors is hopeless due to quadrupolar coupling constants (CQ) on the order of GHz. We ...
