本文报道了用双光束激光光谱仪测量乙烯在λ = 1.6 μ m的v（5）+ v（9）组合振动带的吸收光谱。光谱仪用于找到具有乙烯分子的所有四个核自旋异构体的良好分辨吸收线的光谱的一部分。这些吸收线的旋转量子数和乙烯分子的核自旋异构体负责他们被确定。
We report the making of a double-beam laser spectrometer to measure absorption spectra in the v(5) + v(9) combination vibrational band of ethylene in the region of lambda= 1.6 mu m. The spectrometer is used to find a portion of the spectrum that has well-resolved absorption lines of all tour nuclear spin isomers of ethylene molecules. The rotational quantum numbers of these absorption lines and the nuclear spin isomers of ethylene molecules responsible for them are identified.
