The electric quadrupole coupling constants eqQ/h of 20Na (I π = 2+, T1/2 = 449.7 ms), 21Na (Iπ = 3/2, T1/2 = 22.49 s) and 25Na (I π = 5/2, T1/2 = 59.6 s) in single crystal ZnO and TiO2 were precisely measured by applying the β-NMR technique. The ratio of the quadrupole moments between 20Na (25Na) and 21Na was determined to be 0.728 ± 0.023 (0.011 ± 0.002).
