We find very large Knight shifts, which are dominated by the trivial electron states rather than those associated with the Dirac nodes. However, we also observe an anomalously large increased Knight shift at low temperatures with the field parallel to the\n                    <jats:italic>c<\/jats:italic>\n                    axis in NiTe\n                    <jats:sub>2<\/jats:sub>\n                    , perpendicular to the high mobility carriers. This is explained by a large paramagnetic shift proportional to the Van Vleck susceptibility, with the temperature dependence consistent with rearrangement of the density of states near the Dirac node due to Landau quantization. Density functional theory calculations of the orbital resolved bandstructure were performed to support this result.
