TL;DR: The chemical compositions of SOA produced by photoirradiation of the toluene/NOx/air system in laboratory chamber experiments are analyzed by a combination of liquid chromatography-mass spectrometry, hybrid high-performance liquid Chromatography- mass spectromaetry, and iodometry-spectrophotometry to conclude that the major chemical components of the aerosol are hemiacetal and peroxy hemiacETal oligomers and low-molecular-weight dicar

TL;DR: In this article, the authors investigated the phenol yields in the OH-initiated oxidation of benzene under conditions of low to moderate concentrations of NOx, to elevated NOx levels.

TL;DR: In this paper, the optical properties of secondary organic aerosols (SOAs) generated during photooxidation of toluene in the presence of NOx and the ozonolysis of α-pinene were investigated.

TL;DR: In this article, the complex refractive index (RI, m = n-ki values at 405, 532, and 781 nm of the secondary organic aerosols generated during the photooxidation of toluene (toluene-SOAs) under a variety of initial nitrogen oxide (NOx = NO + NO2) conditions were examined by photoacoustic spectroscopy (PAS) and cavity ring-down spectrography (CRDS).

TL;DR: In this paper, the authors measured the mass spectra of secondary organic aerosol (SOA) formed from the photooxidation of aromatic hydrocarbons using an Aerodyne aerosol mass spectrometer (AMS) and reported that SOA aging is slowed with increasing number of alkyl groups in the precursor molecule.
