Theoretical study of the stability of small triply charged carbon clusters Cn3+ (n=3–12)

Structure, Ionization, and Fragmentation of Neutral and Positively Charged Hydrogenated Carbon Clusters: CnHmq+ (n = 1–5, m = 1–4, q = 0–3)

“…In the present article we studied in a systematic way the properties of neutral and positively charged hydrogenated carbon clusters following our previous theoretical studies for carbon clusters. − Previous theoretical studies have been performed for some of the neutral C n H m ,− and singly charged systems ,− considered in this work. For dications only very specific cases, such as acetylene dication, have been theoretically studied before, and one previous work for trications focuses on pure carbon clusters . Theoretical studies on anionic species have been also reported. ,, In the case of neutral species the information is quite fragmentary, as different authors have only considered specific isomers at different levels of theory.…”
