- Abstract:
- The photolysis quantum yields of formaldehyde, glyoxal and methyl glyoxal will be measured over a range of atmospherically significant wavelengths and as a function of temperature and pressure. Pulsed dye and excimer lasers will be used for photolysis and the parent compounds, CO, HCO, H and CH3CO monitored by a combination of laser induced fluorescence (LIF), cavity ring down spectroscopy (CRDS), tunable infra red diode laser absorption (TDLAS) and GC analysis. The kinetics and mechanism of the oxidation of toluene, under atmospherically relevant conditions, will be investigated by laser flash photolysis probing (i) OH (by LIF), the OH adduct (by CRDS) and the peroxy radical (by near ir CRDS), (ii) OH LIF to determine the yields of HO2 and of secondary OH (iii) the yields of HCHO, glyoxal and methyl glyoxal by TDLAS, CRDS and GC.
