The nuclear magnetic resonance of 91 Zr in hexagonal close-packed Zr metal has been observed in the temperature range of 1.4–4.2 K and in the frequency range of 15–30 MHz by pulsed nuclear resonance technique. The resonance line profile showed a well resolved powder pattern due to electric quadrupole interaction. The quadrupole coupling constant was determined to be e 2 q Q / h =18.7±0.3 MHz. The isotropic Knight shift and the nuclear spin-lattice relaxation time were measured to be 0.33±0.02% and ( T 1 T )=30±5 sec K respectively and were discussed in terms of hyperfine interactions with the s- and d-band electrons.
