For the HF, HCl AND HBr dimers, and their deuterated forms, we have calculated the positions and intensities of the trans-bend, cis-bend and torsional bands using purely electrostatic potential energy functions, and the monomer dipole moments. For the case of the HF dimer we have also done the calculation using the most recent ab initio potential of Bunker $etal1$. The calculations have been performed with the intermolecular bond lengths and the HX bond lengths fixed. The results of the calculations will be compared with cach other and with experiment
