Computed absorption spectra (f-values) of three isomers of fullerene C₅₀ (Table B.2). The results of complete calculations from ~350 to 2000 nm for the isomers of neutral C₅₀ (D_5h, 271; D₃, 270; and C_s, 266) are displayed by open symbols, together with the cation spectra (C_5h, 271; C₂, 270; and C_s, 266) from ~500 to 2000 nm (full symbols). See similar Figs. B.1–B.4 for isomers of C₄₀, C₄₂, C₄₄, C₄₆, and C₄₈ listed in Table B.2.
