2 O)、二氧化碳(CO2)和二氧化硫(SO2)。CO,N2 O,和CO2的实时检测进行了开放空气中的路径长度为5至18米。本文还研究了用差分荧光光谱法测量大气CO2中13 C/12 C和18 O/17 O/16 O同位素比值的可行性。据我们所知,我们报告的是第一次同时光谱测量的所有三种同位素的氧在环境中的二氧化碳。
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.
