High-spin states in 79Rb were populated in the reaction $\mathrm{^{63}Cu \ensuremath(^{19}F, p2n) ^{79}Rb}$ at E(beam) = 60 MeV. The lifetimes of the excited states of the $\pi \ensuremath g_{\frac{9}{2}}$ positive-parity yrast band and of the $\pi \ensuremath p_{\frac{3}{2}}$ negative-parity band in 79Rb were measured by the Doppler Shift Attenuation Method. The deduced transition quadrupole moments Qt are found to have a decreasing trend with rotational frequency for both the bands, consistent with those found experimentally in neighbouring nuclei.
