The infrared absorption cross sections of ethane (C₂H₆) have been measured in the 3.3 µm region by high resolution Fourier transform spectroscopy. The ethane samples had temperatures of 203, 233, 263, 295 K with broadening gas pressures of 10 Torr, 30 Torr and 100 Torr of hydrogen or helium. These cross sections are useful for the interpretation of spectra of the giant planets.

氢和氦在3.3微米范围内扩大的乙烷吸收截面

乙烷（C ₂ H ₆）的红外吸收截面已通过高分辨率傅里叶变换光谱法在3.3 µm范围内进行了测量。乙烷样品的温度为203、233、263、295 K，加宽的氢气或氦气压力为10托，30托和100托。这些横截面对于解释巨型行星的光谱很有用。
