The radioactive decay of ^{172}Lu → ^{172}Yb appears to be suitable for time-differential perturbed angular correlation measurements of quadrupole interaction. The technique was applied to study various phenomena in three compounds: Yb_3S_4, YbPO_4, Yb_2Co_3Ga_9. We were able to distinguish between Yb^{2+} and Yb^{3+} ions occupying different positions in the crystal lattice of Yb_3S_4. Crystal electric field parameters reproduced the temperature dependence of the quadrupole interaction of Yb in YbPO_4. Finally, the influence of hybridization on the 4f quadrupole moment in Yb_2Co_3Ga_9 is evidenced.
