Abstract: Soot samples from a spark generator, a flame and a diesel passenger car were collected and investigated by Fourier transform infrared (FTIR) spectroscopy mounting on 10 cm vacuum cell connected to a standard flow system with He as carrier gas. The reaction probability on diesel engine soot was of slower magnitude and the reaction of soot with NO2 cannot account for the HONO levels observed in urban air.
