Recent band structure calculations predict that YPdBi is topologically trivial while its isostructural analogue YPtBi is topologically nontrivial. 209Bi nuclear magnetic resonance spectroscopy is employed to investigate the atomic and electronic structures of both compounds and test this theoretical hypothesis. The observed sign and magnitude of 209Bi isotropic shifts of YPtBi at various temperatures are systematically distinct from YPdBi. Combined with Hall effect measurements, these results support the band inversion model.
