Infrared Absorption Spectrum of Methane From 2470 to 3200 cm(−1)

The absorption spectrum of methane has been measured from 2470 to 3200 cm(−1) with a high-resolution infrared spectrometer. Pressures from 0.01 to 4.5 cm of the gas were used in order to observe both intense and weak lines. A total of 2,460 lines were measured in the entire region. The v(3) band at...

Sumario:The absorption spectrum of methane has been measured from 2470 to 3200 cm(−1) with a high-resolution infrared spectrometer. Pressures from 0.01 to 4.5 cm of the gas were used in order to observe both intense and weak lines. A total of 2,460 lines were measured in the entire region. The v(3) band at 3018 cm(−1) was measured at very slow scanning rates and the lines of the P and R branches were resolved into several components. The observed spectrum is shown in five figures.
