The interaction of NO2 with organic interfaces is critical in the development sensing and trapping technologies, equally so to atmospheric processing marine continental aerosol. Recent studies point importance surface oxygen groups these systems, however role specific functional on microscopic level has yet be fully established. In present study, we aim provide fundamental information behavior at atmospherically relevant that may also help inform innovation development. We then an investigation into structural changes induced by propylene carbonate (PC), environmentally ester. Surface-sensitive spectra PC liquid are acquired before, during, after exposure using infrared reflection-absorption spectroscopy (IRRAS). Spectra reveal preferentially interacts carbonyl interface, forming a distribution binding symmetries. At low ppm levels, saturates within 10 minutes perturbations constant over time during flow NO2. Upon removal flow, under pressures, interactions reversible, structure recovers completely 30 min. Another ester-containing molecule, diethyl sebacate (DES), was investigated same carbonyl-specific intermittently observed.
