In this paper we report calculations of the relativistic corrections totransition frequencies (q factors) of Yb II for the transitions from theodd-parity states to the metastable state $4f^{13}6s^2 ^2F_{7/2}^o$. Thesetransitions are of particular interest experimentally since they possess someof the largest q factors calculated to date and the $^2F_{7/2}^o$ state can beprepared with high efficiency. This makes Yb II a very attractive candidate forthe laboratory search for variation of the fine-structure constant alpha.
