New MiZo line lists are presented for the D2H+ and D3+ isotopologues of H3+. These line lists plus the existing H3+ MiZATeP and the Sochi H2D+ line lists are updated using empirical energy levels generated using the MARVEL procedure for H3+, H2D+ and D2H+, and effective Hamiltonian energies for D3+ for which there is significantly less laboratory data available. These updates allow accurate frequencies for far infrared lines for these species to be predicted. Assignments of the energy levels of H3+ and D3+ are extended using a combination of high accuracy variational calculations and analysis of transition intensities. All line lists are made available via www.exomol.com.
