Description We propose to perform deep integrations for a significant detection of the 13CII and 13CI hyperfine transitions towards five PDRs where previous observations showed marginal, inconsistent or particularlypuzzling results. These included anomalous hyperfine ratios andstrong variations of the fractionation within one source. The observations will measure the absolute C+ fractionation, they willallow to distinguish the effects of isotope-selective photodissociationand chemical fractionation, and constrain the total isotopic ratio of 13C to 12C.

    Mission Description Herschel was launched on 14 May 2009! It is the fourth cornerstone mission in the ESA science programme. With a 3.5 m Cassegrain telescope it is the largest space telescope ever launched. It is performing photometry and spectroscopy in approximately the 55-671 µm range, bridging the gap between earlier infrared space missions and groundbased facilities.
