Fig. 6: Nitrate-CIMS spectra for α-pinene ozonolysis.
From: Molecular mechanism for rapid autoxidation in α-pinene ozonolysis

The experiments carried out at reaction times 75 ms (a, c) and 300 ms (b) indicate rapid formation of peroxy radical C10H15O8. The background peak at 75 ms in a is expanded in c. Blue labels indicate radical and green labels indicate closed-shell species derived from α-pinene ozonolysis. Red label indicates possible radical species from OH oxidation of α-pinene.
