Optical emissions from excitation of small aerosols by excimer laser photons in the UV region are investigated. The aerosols are produced from reactions of O3 with various hydrocarbons, such as 1-butene, 1,3-butadiene, trans- and cis-2-butenes, propylene, and ethylene in a flow tube, which is made of a PVC pipe of 5-cm i.d. and 100 cm long. The aerosol sizes produced in the few tube are mostly in the few hundred angstrom range.
