Fig. 3. — Photoionization mass spectra and photoionization efficiency spectra of C₁₀H₂₀O₃, C₁₀H₁₈O₄, and C₁₀H₂₀O₅ with and without D₂O addition. (A–C) Mass spectra of C₁₀H₂₀O₃, C₁₀H₁₈O₄, and C₁₀H₂₀O₅ with (dashed red line) and without D₂O addition (black line) at 530 K and 9.5 eV. (D–F) Photoionization efficiency spectra of C₁₀H₂₀O₃, C₁₀H₁₈O₄, and C₁₀H₂₀O₅ (open symbols) and their corresponding deuterated species (lines) at 530 K. Signal of C₁₀H₂₀O₅ in F multiplied by 2.3.
