10‐Methylacridine dimer [(AcrH) 2 ] dissociates into a pair of 10‐methylacridyl radicals (AcrH˙) on laser excitation (308 nm) in solvents of various polarities. Exposure of (AcrH) 2 in methylcyclohexane glass at 77 K to γ‐rays of 60 Co generates the radical cation (AcrH) 2 +˙ . Thermal annealing of the matrix to 90 K results in dissociation of (AcrH) 2 +˙into AcrH˙ and 10‐methylacridinium cation (AcrH + ).
