| Abstract |
An analytical and experimental investigation has been carried out to determine the feasibility of using the scattering of ultraviolet radiation by SO2 as a probe of the concentration of that molecule in stationary source emissions. Both ordinary fluorescence and resonant Raman scattering were considered and experimentally it was found that the latter component was present in the scattered radiation with sufficient magnitude to reduce significantly the degrading effect that ordinary fluorescent quenching has on this scattering technique. Further analysis revealed that current state-of-the-art dye lasers deliver sufficient ultraviolet pulse energy to permit SO2 concentration determination in practical situations but that fluorescent scattering from particulates presents a possible constraint to the validity of this technique. A field program is recommended to investigate the latter. |
