Spin-orbit coupling (SOC) is expected to partly determine the topologicallynontrivial electronic structure of heavy half-Heusler ternary compounds.However, to date, attempts to experimentally observe either the strength of SOCor how it modifies the bulk band structure have been unsuccessful. By usingbulk-sensitive nuclear magnetic resonance (NMR) spectroscopy combined withfirst-principles calculations, we reveal that 209Bi NMR isotropic shifts scalewith relativity in terms of the strength of SOC and average atomic numbers,indicating strong relativistic effects on NMR parameters. According tofirst-principles calculations, we further claim that nuclear magneticshieldings from relativistic p1/2 states and paramagnetic contributions fromlow-lying unoccupied p3/2 states are both sensitive to the details of bandstructures tuned by relativity, which explains why the hidden relativisticeffects on band structure can be revealed by 209Bi NMR isotropic shifts intopologically nontrivial half-Heusler compounds. Used in complement tosurface-sensitive methods, such as angle resolved photon electron spectroscopyand scanning tunneling spectroscopy, NMR can provide valuable information onbulk electronic states.
