N2 - Photoproducts resulting from illumination of a pyrene-chloroform solution using several light sources (sunlight, lamp, a pulsed laser) were analyzed by using gas chromatography (GC) and GC-mass spectrometry. The main photoproducts in chloroform were chloropyrene and pyrenecarboxaldehydes, and their relative yields depended on differences in illumination conditions. Chloropyrene was formed under all types of light illumination, while ultraviolet lights was required for the formation of pyrenecarboxaldehydes. Several reaction mechanisms are proposed to account for the formation of chloropyrene and pyrenecarboxaldehydes.
