• Our astrochemical heritage (2012, background): “…propylene (CH2CHCH3 Marcelino et al. 2007), methyldiacetylene (CH3C4H), cyanopolyynes (HC2n+1N, n = 0,1, . . . ,5) and C2n+1N radicals (Walmsley et al. 1984; Hirahara et al. 1992; Ohishi and Kaifu 1998; Kaifu et al. 2004) and the negative ions C6H−, C8H− (McCarthy et al. 2006; Brünken et al. 2007).”
• Astronomical identification of CN^-, the smallest observed molecular anion (2010, background): “The C2H− and CN− anions are closed-shell molecules whose rotational spectrum has been recently measured in the laboratory (Brünken et al., 2007b; Gottlieb et al., 2007; Amano, 2008).”
• The UMIST database for astrochemistry 2012 (2012, background): “Since then, it and other anions have been detected in a variety of sources (Brünken et al. 2007; Remijan et al. 2007; Sakai et al. 2010b; Cordiner et al. 2011).”
• Negative ion chemistry in Titan's upper atmosphere (2008, background): “While CN and C2H form relatively stable negative ions (see Section 3.1), the concentrations of these radicals, as calculated by Capone et al. (1980) and Yung et al. (1984), are too small for them to be a significant source of negative ions.”
• 2018 Census of Interstellar, Circumstellar, Extragalactic, Protoplanetary Disk, and Exoplanetary Molecules (2018, methodology): “Brünken et al. (2007) observed the 11 → 10 through 13 → 12, and the 16 → 15 transitions between 12.8–18.7 GHz, based on the same laboratory work.”
• Laboratory and Astronomical Detection of the Negative Molecular Ion C3N− (2008, methodology): “TMC-1 The recent observations of C6H and C8H in TMC-1 with abundances of a few percent that of the corresponding radical (McCarthy et al. 2006; Brünken et al. 2007), suggested that C3N might be detected in this source.”
