The experimental data available for the photodissociation quantum yields of acetaldehyde are evaluated to derive formal expressions for their dependence on wavelength and pressure. The formulae are used to calculate the photodissociation coefficient

The quantum yields for CO and CH(4), formed in the photolysis of about 200 μmol mol(-1) of acetaldehyde in air at atmospheric pressure, were determined at 15 wavelengths in the range: 250-330 nm. The quantum yields for CO(2) were determined at nine

A new method has been applied to determine OH-radical yields from the ozonolysis of both double bonds from five selected, atmospherically relevant monoterpenes, namely terpinolene, α-phellandrene, limonene, α-terpinene and γ-terpinene. While OH-yi

The temperature dependence of secondary organic aerosol (SOA) formation from ozonolysis of β-pinene was studied in a flow reactor at 263 K–303 K and 1007 hPa under dry and humid conditions (0% and 26%–68% relative humidity, respectively). The ob

4-Oxopentanoic acid was characterized experimentally by electrospray ionization using a triple quadrupole and time-of-flight analyzer hybrid system. This compound was chosen as a model substance for small organic compounds bearing an acetyl and a car

An important fraction of secondary organic aerosol (SOA) formed by atmospheric oxidation of diverse volatile organic compounds (VOC) has recently been shown to consist of high-molecular weight oligomeric species. In our previous study (Sadezky et al.

The components of the organic aerosol formed due to gas-phase beta-caryophyllene ozonolysis were characterized by the use of a triple quadrupole and time-of-flight analyzer hybrid system coupled to an electrospray ionization source operated in the ne
