ExoMol line lists - L: high-resolution line lists of H3+, H2D+, D2H+, and D3+

New MiZo line lists are presented for the D2H+ and D-3(+) isotopologues of H-3(+) . These line lists plus the existing H-3(+) MiZATeP and the ST H2D+ line lists are updated using empirical energy levels generated using the MARVEL procedure for H-3(+) , H2D+, and D2H+, 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 av ailable via www.exomol.com .
