We use the relativistic Hartree-Fock method, many-body perturbation theory, and configuration-interaction method to calculate the dependence of atomic transition frequencies on the fine-structure constant $\ensuremath{\alpha}={e}^{2}∕\ensuremath{\hbar}c$. The results of these calculations will be used in the search for variation of the fine-structure constant in quasar absorption spectra.
