Detection of C8H– and Comparison with C8H toward IRC +10 216 (2007, methodology): “The detection was further confirmed by observing two Ku-band transitions toward TMC-1 (McCarthy et al. 2006) with the GBT. Kasai et al. (2007) followed up on the initial 1995 survey results and detected two new transitions of C6H at 7 and 3 mm wavelengths using the Nobeyama 45 m and IRAM 30 m radio ”
Detection of the Carbon Chain Negative Ion C8H– in TMC-1 (2007, neutral): “…by Kawaguchi et al. (1995) in the circumstellar envelope of the evolved carbon star IRC 10 216 and the detection of this anion in the dark molecular cloud TMC-1 have renewed interest in molecular anions with respect to laboratory, observational, and astrochemical studies (McCarthy et al. 2006).”
Astrochemistry and compositions of planetary systems (2020, background): “This produces a mixture of species due to multiple dissociation products and/or subsequent chemistry, and the resulting spectra need to be carefully analyzed to identify the lines belonging to the target molecule (e.g. McCarthy et al. 2006; Bizzocchi et al. 2017).”
Detection of C5N− and Vibrationally Excited C6H in IRC +10216 (2008, background): “C6H − has already been detected in the laboratory and in IRC+10216 (McCarthy et al., 2006), and is immediately ruled out.”
Astronomical identification of CN^-, the smallest observed molecular anion (2010, background): “…heavy linear carbon chains with three or more carbon atoms, and with neutral counterparts with large electron affinities: C4H−, C6H−, C8H−, C3N−, and C5N− (McCarthy et al., 2006; Cernicharo et al., 2007; Brünken et al., 2007a; Remijan et al., 2007; Thaddeus et al., 2008; Cernicharo et al., 2008).”
Laboratory and Astronomical Detection of the Negative Molecular Ion C3N− (2008, background): “Negative molecular ions, however, have only been known for just over one year; the first, C6H , was shown on the basis of laboratory measurements (McCarthy et al. 2006) to be the carrier of an unidentified series of lines in IRC+10216 (Kawaguchi et al. 1995).”
The UMIST database for astrochemistry 2012 (2012, background): “In 2006, C6H− was discovered in the Taurus Molecular Cloud 1 (TMC-1) by McCarthy et al. (2006).”
2018 Census of Interstellar, Circumstellar, Extragalactic, Protoplanetary Disk, and Exoplanetary Molecules (2018, background): “A substantial amount of laboratory (e.g., Linnartz et al. 2015 and Fedoseev et al. 2015), quantum chemical (e.g., Woon 2002), and chemical modeling (e.g., Garrod et al. 2008) work suggests that these hydrogenation processes are efficient in the ISM, often even at low temperatures.”
