Resonance stabilised free radicals (RSFRs) play an important role in the growth of polycyclic aromatic hydrocarbons and ultimately in the production of soot and carbonaceous particles in combustion flames, in the interstellar medium, and in planetary atmospheres. This article reviews extensive experimental crossed molecular beams and theoretical ab initio/Rice–Ramsperger–Kassel–Marcus studies in the last two decades of the reactions of atomic carbon, C(3P), dicarbon, C2(X1Σg+/a3Πu), and tricarbon, C3(X1Σg+), with unsaturated hydrocarbons, from acetylene to benzene, showing that the reactions form various types of RSFR via Cn(n = 1–3)-for-H, Cn-for-CH3, and Cn-for-CxHy exchange mechanisms. The RSFRs produced in these reactions include CxH (x = 1–8), propargyl (C3H3) and its substituted analogues, 2,4-pentadiynyl-1 (i-C5H3) and 1,4-pentadiynyl-3 (n-C5H3) together with their methyl substituted counterparts, butatrienyl (i-C4H3) and its substituted analogues, and hexenediynyl, i-C6H3, as well as cyclic five-,...
