In this work we study the last two hydrogen molecular ion isotopologues, DT+ and T2 +, for which high-precision calculations have not yet been made. We obtain the nonrelativistic solutions of the Schrödinger equation for the wide range of vibrational states up to the highest possible vibrational 1sσg state which are of spectroscopic precision. Transition amplitudes for electric dipole transitions, leading-order relativistic corrections, and coefficients of the effective hyperfine structure Hamiltonians for both DT+ and T2 + are also calculated.
