The surface activity of ten atmospherically relevant α-pinene-derived dimers having varying terminal functional groups and backbone stereochemistry is reported. We find ~10% differences in surface activity between diastereomers of the same dimer, demonstrating that surface activity depends upon backbone stereochemistry. Octanol-water (KOW) and octanol-ammonium sulfate partitioning coefficient (KOAS) measurements of our standards align well with the surface activity measurements, with the more surface-active dimers exhibiting increased hydrophobicity. Our findings establish a link between molecular chirality and cloud activation potential of secondary organic aerosol particles. Given the diurnal variations in enantiomeric excess of biogenic emissions, possible contributions of such a link to biosphere:atmosphere feedbacks as well as aerosol particle viscosity and phase separation are discussed.

Abstract: Treatment of peroxide ozonolysis products of the bicyclic monoterpenes (–)-α-pinene and (+)-3-carene with 4-hydroxybenzohydrazide in methylene chloride or tetrahydrofuran gave the corresponding keto acids, whereas keto esters were formed in methanol.

The reactivities of hydrazines of HCl and H2SO4 for (-)-α-pinene peroxide ozonolysis products were studied. It was shown that these reagents were less effective and selective than semicarbazide hydrochloride for transformations into cis-pinonic acid and its esters.
