The Ubiquitous Nature of HF
Abstract
Of the several molecules newly discovered, or whose lines have been observed for the first time with HIFI on the Herschel satellite, the HF (1-0) rotational transition appears to be one of the most often observed around the Galaxy. This was anticipated from the very high (>1 THz) frequency of the ground state transition indicating the strong chemical bond and high dissociation energy which implies that the HF molecule is difficult to destroy, once created. In this case it could well prove to be a good tracer for H2. Here we examine the estimated abundance as a fraction of the distance from the Galaxy center for a set of objects including Orion (OMC1), SgrB2, W49, W51, G34.3, G10.6.
