pre-print
We present a charge distribution based model that computes the infrared spectrum of polycyclic aromatic hydrocarbon (PAH) molecules using recent measurements or quantum chemical calculations of specific PAHs. The model is applied to a sample of well-studied photodissociation regions (PDRs) with well-determined physical conditions (the radiation field strength, G_0, electron density n_e, and the gas temperature, T_ gas). Specifically, we modelled the emission of five PAHs ranging in size from 18
