Abstract (from CDS):

The results of a Caltech Submillimeter Observatory (CSO) search for l-C3H+, first detected by Pety et al. in observations towards the Horsehead photodissociation region (PDR), are presented. A total of 39 sources were observed in the 1 mm window. Evidence of emission from l-C3H+ is found in only a single source - the Orion Bar PDR region - which shows a rotational temperature of 178(13) K and a column density of 7(2)x1011/cm2. In the remaining sources, upper limits of ∼ 1011-1013/cm2 are found. These results are discussed in the context of guiding future observational searches for this species.
