Stark-induced amplitudes for the 6P1∕2\text\ensuremath-7P1∕2 transition in Tl\phantom\rule0.2em0exI are calculated using the relativistic singles-doubles (SD) approximation in which single and double excitations of Dirac-Hartree-Fock levels are summed to all orders in perturbation theory. Our SD values \ensuremathαS=368a03 and \ensuremath|\ensuremathβS\ensuremath|=298a03 are in good agreement with the measurements \ensuremathαS=377(8)a03 and \ensuremathβS=313(8)a03 by D. DeMille, D. Budker, and E. D. Commins [Phys. Rev. A 50, 4657 (1994)]. Calculations of the Stark shifts in the 6P1∕2\text\ensuremath-7P1∕2 and 6P1∕2\text\ensuremath-7S1∕2 transitions are also carried out. The Stark shifts predicted by our calculations agree with the most accurate measured values within the experimental uncertainties for both transitions.
