| Zusammenfassung |
| The build-up of oligomeric compounds during secondary organic aerosol (SOA)
formation is subject of atmospheric research since several years. New
particle formation and especially the SOA mass yield might be influenced
significantly by oligomer formation. However, the chemical nature of
observed oligomers and their formation pathways are still unclear. In this
paper, the structural characterization of certain dimeric compounds (esters)
formed during the ozonolysis of cyclohexene and cyclohexene/α-pinene
mixtures are presented. The identification is based on the comparison of the
mass spectra and the retention times (LC) of the oligomeric products with
synthesized reference compounds. Cyclohexene is used here as a model
compound for terpenes as globally most important SOA precursors, since it
possesses a simpler structure than the biogenic alkenes and therefore offers
the possibility to get access to reference compounds for certain of its
oxidation products. In addition to cyclohexene, the formation of esters
could also be observed in experiments with α-pinene as reactant. |
