The SPIRE Fourier Transform Spectrometer on-board Herschel allows us, for the first time, to simultaneously measure the complete far-infrared spectrum from 194 to 671 μm. A wealth of rotational lines of CO (and its isotopologues), fine structure lines of C^0 and N^+, and emission lines from radicals and molecules has been observed towards several galactic regions and nearby galaxies. The strengths of the atomic and molecular lines place fundamental constraints on the physical conditions but also the chemistry of the interstellar medium. FTS mapping capabilities are also extremely powerful in characterizing the spatial morphology of the extended region and understand how the gas properties vary within the studied region. Here, we present a first analysis of SPIRE spectroscopic observations of the prototypical Orion Bar photodissociation region.
