Zusammenfassung:	<jats:p>The time differential perturbed angular correlation (TDPAC) technique has been used to study the nuclear quadrupole interactions of the first excited state of ground state rotational band (2<jats:sup>+</jats:sup>, 80 keV, T<jats:sub>1/2</jats:sub> = 1.88 ns) and the band head of the = 4<jats:sub>1</jats:sub> <jats:sup>-</jats:sup> band (4<jats:sub>1</jats:sub> <jats:sup>-</jats:sup>,1094 keV, T<jats:sub>1/2</jats:sub> = 120 ns) in the <jats:sup>168</jats:sup>Er nucleus of a polycrystalline Er host. At room temperature we obtained the electric quadrupole interaction frequencies ω<jats:sub>0</jats:sub>(K= 0) = 457(15) Mrad/s and ω<jats:sub>0</jats:sub>(K= 4) = 69(2) Mrad/s, respectively, for the 2<jats:sup>+</jats:sup> and 4<jats:sup>-</jats:sup> isomeric states of <jats:sup>168</jats:sup>Er. The ratio of the spectroscopic quadrupole moments, i. e. Q<jats:sub>s</jats:sub> (K= 4)/Q<jats:sub>s</jats:sub> (K= 0) = 0.69(3), is independent of any model approximation and the electric field gradient at <jats:sup>168</jats:sup>Er in the host metal</jats:p>
