We have initiated the first $^{17}$ O-NMR measurements in the ordered state of NpO. From the $^{17}$ O-NMR spectrum, we have confirmed the occurrence of two inequivalent oxygen sites below = 26 K. It has also been shown that the $^{17}$ O-NMR spectrum in the ordered state can be understood by considering an unconventional hyperfine interaction between the $^{17}$ O nuclear spins and field-induced antiferromagnetic moments arising from the longitudinal triple- antiferro-quadrupolar order. These NMR results give strong evidence for the occurrence of the longitudinal triple- multipole structure in NpO.
