  New MiZo line lists are presented for the D$_2$H$^+$ and D$_3^+$
isotopologues of H$_3^+$. These line lists plus the existing H$_3^+$ MiZATeP
and the Sochi H$_2$D$^+$ line lists are updated using empirical energy levels
generated using the MARVEL procedure for H$_3^+$, H$_2$D$^+$ and D$_2$H$^+$,
and effective Hamiltonian energies for D$_3^+$ 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 H$_3^+$ and D$_3^+$ 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.
