... We give a brief introduction to the physics and chemistry of photon dominated regions (PDRs) and the state of art of theoretical PDR modelling. We present observations of the [CII] and line emission of the Rosette Molecular Cloud. ... The theory states that these FUV photons determine the chemical and physical conditions of the cloud, creating a so called p hoton d ominated r egion (PDR, in earlier papers also named photodissociation region) on the surface of individual molecular clumps. ...
