Fig. 1: Molecular structures of three resonantly stabilized free radicals (RSFRs).

From: Unconventional excited-state dynamics in the concerted benzyl (C7H7) radical self-reaction to anthracene (C14H10)

Propargyl (C3H3•, X2B2), cyclopentadienyl (C5H5•, X2B2), and benzyl (C7H7•, X2B2) are contemplated as key precursors to polycyclic aromatic hydrocarbons (PAHs) in high temperature molecular mass growth processes. Carbon and hydrogen atoms are color coded in gray and white, respectively.
