      abstract     = {In the atmosphere, both gas and particle phase organic
                      trace compounds (OTC) have multiple effects on air quality
                      and climate. Gaps exist in a fundamental understanding of
                      the sources and sinks of organics and thus, knowledge needed
                      to steer regulatory purposes is far from complete. Isotopes
                      provide specific “fingerprints” in OTC. These
                      fingerprints result from the isotopic composition at
                      emission, as well as from chemical and physical processes in
                      the atmosphere. Compound specific isotope ratio mass
                      spectrometry (IRMS) in atmospheric OTC is therefore a
                      promising tool to improve our understanding of sources and
                      the atmospheric fate of OTC. Due to analytical challenges
                      originating from the small sample amounts and a huge variety
                      of physical and chemical properties of OTC present in the
                      atmosphere, such measurements are not routinely performed.
                      We present an overview of basic concepts as well as
                      instrumental and measurement procedures used for compound
                      specific IRMS in atmospheric OTC. Concepts for the
                      interpretation of ambient observations are reviewed together
                      with available literature data on source specific and
                      ambient δ13C values of gas and particle phase OTC. Full
                      deployment of the IRMS potential in future atmospheric
                      studies will depend on the availability of laboratory
                      kinetic data. Further method developments, such as
                      increasing sensitivity and accuracy, as well as techniques
                      for simultaneous isotope ratio measurement of multiple atoms
                      are expected to further extend the potential use of isotope
                      ratios for studies of atmospheric OTC.},
