2O), carbon dioxide (CO2), and sulfur dioxide (SO2). Real-time detection of CO, N2O, and CO2was performed in open air over a path length of 5 to 18 m. The feasibility of DFG spectroscopic measurement of the13C/12C and18O/17O/16O isotopic ratios in atmospheric carbon dioxide was also investigated. We report what to our knowledge is the first simultaneous spectroscopic measurement of all three isotopes of oxygen in ambient CO2.
