The rate of star formation is enhanced in many galaxies that show disturbed morphology and/or evidence of interaction. However, the physical explanation of this connection has proved elusive, since it appears that peculiar morphology of a specific type is neither necessary nor sufficient to promote star formation. To explore the relation between star formation rates and galaxy morphology we have selected a sample of galaxies from the Arp-Madore Catalogue of Southern Peculiar Galaxies and Associations (AMC) and the Principle Galaxy Catalogue (PGC), and estimated their star formation rate using the far-infra-red (FIR) power listed in the QMW IRAS Galaxy Catalogue (QMCIGC). There are 933 objects common to all three catalogues, potentially providing the necessary data for the peculiar galaxies.
