A smog chamber made of Teflon film with a volume of approximately 2 m<SUP>3</SUP> was used for the experiments of aerosol generation by photoirradiation to α-pinene-NO<SUB>x</SUB> -dry air system. The generated aerosol was analyzed by FT-IR, GC/MS and GC/IR. Hydroxyl, carbonyl and organonitrate functional groups were detected from the aerosol. A group of the products with a volatility lower than pinonic acid were identified with dicarboxylic acids including pinic acid (3-carboxy-2, 2-dimethylcyclobutaneacetic acid) . IR absorption of acid anhydride or cyclic ester was detected from some products. By the photooxidation of α-pinene (1.32 ppm) with NO<SUB>x</SUB> (0.78 ppm) , pinic acid was produced even after the consumption of α-pinene with the final formation yield of 0.74%. This suggests that pinic acid is produced from reaction of α-pinene with ozone either directly or through oxocarboxylic acid.
