α dependence of transition frequencies for some ions of Ti, Mn, Na, C, and O and the search for variation of the fine-structure constant

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 α=e²∕c. The results of these calculations will be used in the search for variation of the fine-structure constant in quasar absorption spectra.
