Accurate rotational-vibrational line lists for two isotopologues of PN in their ground electronic states are computed. The line lists are produced using an empirical potential energy curve obtained by fitting to the experimental transition frequencies available in the literature in conjunction with an accurate, high level ab initio dipole moment curve. In these calculations the programs DPotFit and LEVEL 8.0 were used. The new line lists reproduce the experimental wavenumbers with a root-mean-square error of 0.004cm^-1^. The line lists cover the frequency range 0-51000cm^-1^, contain almost 700000 lines each and extend up to a maximum vibrational level of v=66 and a maximum rotational level of J=357. They should be applicable for a large range of temperature up to, at least, 5000K. These new line lists are used to simulate spectra for PN at a range of temperatures and are deposited in the Strasbourg data centre. This work is part of the ExoMol project (2012MNRAS.425...21T).
