Short summary
High-molecular-weight esters present in α-pinene ozonolysis secondary organic aerosol have been structurally characterized with electrospray ionization mass spectrometry. Unambiguous evidence could be obtained for the linkage in the MW 368 hydroxypinonyl ester of pinic acid, while the same linkage could be supported for the MW 358 diaterpenylic ester of pinic acid. A mechanistic proposal is presented to explain their possible formation from highly oxygenated molecules reported in previous work.
