|Abstract:||This lecture will focus on several experimental approaches under development in our laboratory to address relevant problems of interest for both homogeneous and heterogeneous atmospheric chemistry. Laser Photofragmentation (LPF) and Laser Induced Fluorescence (LIF) are used to study the oxidation mechanism of Dimethyl Sulphide (DMS), leading to the formation of sulphuric acid aerosols. These aerosols, generated in the laboratory by homogeneous nucleation, are characterised with a Differential Mobility Analyser before entering the laser excitation volume. Time resolution of the resu;lting emission, which could be ascribed to sulphur dioxide adsorbed on the aerosol surface, is performed with a gated Optical multichannel Analyser.|
