We discuss the first astronomical detection of the CF + (fluoromethylidynium) ion, obtained by observations of the J = 1− 0 (102.6 GHz), J = 2− 1 (205.2 GHz) and J = 3− 2 (307.7 GHz) rotational transitions toward the Orion Bar region. Our search for CF + - carried out using the IRAM 30m and APEX 12m telescopes - was motivated by recent theoretical models that predict CF + abundances of few× 10 −10 in UV-irradiated molecular regions where C + is present. The CF + ion is produced by exothermic… Expand
