A carbon dioxide laser source was used to determine absorption coefficients for dilute absorber-air mixtures at wavelengths corresponding to several vibration-rotation lines in each branch of the 00 degrees 1-02 degrees 0 band at 9.4 microm and the 00 degrees 1-10 degrees 0 band at 10.4 microm. For all samples the total pressure was 1 atm and the temperature was 300 K; the concentrations ranged from 10 ppm (parts per million by volume) to 357 ppm for NH(3) and C(2)H(4), and from 10 ppm to 80 ppm for O(3). The absorption coefficients are tabulated, and the use of selected laser lines in monitoring ambient concentrations is discussed.
使用二氧化碳激光源测定了在9.4微米处00°1-02°0带各分支以及10.4微米处00°1-10°0带中对应于几条振动-转动谱线的波长下，稀释吸收剂-空气混合物的吸收系数。对于所有样品，总压力为1个大气压，温度为300K；NH₃和C₂H₄的浓度范围为10ppm（百万分比体积）至357ppm，O₃的浓度范围为10ppm至80ppm。列出了吸收系数，并讨论了在监测环境浓度中使用选定激光谱线的情况。
