Short Abstract: This paper presents the study of polycyclic aromatic hydrocarbons (PAH) and paramagnetism of soot particles sampled from cool sooting flames of methane and propane in a separately-heated two-sectional reactor under atmospheric pressure at the reactor temperatures of 670-1170 K. The temperature profiles of the flames were studied. The sampling was carried out with a quartz sampler and the samples were frozen with liquid nitrogen. A number of polyaromatic hydrocarbons such as pyrene, fluorantene, coronene, anthantrene, 1,12-benfherylene, were identified by spectroscopic methods in the extract of soot. In order to explain experimental results we have performed numerical model of formation PAH at burning of methane. The accounts kinetics of burning of methane on a basis of kinetics scheme was executed. For accounts previously were designed a molar heat of formation of intermediate connections and are picked up kinetics of elementary constant reactions
