An experimental study has been conducted of effects of materials, spectrum, surface/volume ratio (S/V) and cleaning technique on the photochemical reactions observed in a smog chamber. A unique chamber and lighting system was used, which permitted independent variation in chamber materials and in light conditions. A xenon arc lamp-parabolic reflector combination provided a collimated light beam. By orienting plates of materials parallel to the beam, it was possible to independently vary light conditions and materials.
