Short summary
Evidence is provided that the green leaf aldehydes 2-E-pentenal, 2-E-hexenal, and 3-Z-hexenal are precursors for secondary organic aerosol, namely, organosulfates with MWs 230, 214, and 170. The structures were elucidated with liquid chromatography/(−)electrospray ionization mass spectrometry (MS), involving accurate mass measurements and ion trap MS. It is shown that the MW 214 isomer with the sulfate group at the C-2 position is unstable and decarboxylates to a MW 170 organosulfate.
