Infrared absorption cross sections for hot isobutane in the CH stretching region
Abstract
Abstract Spectra of pure isobutane were recorded at high temperature in the C-H stretching region (2750-3050 cm−1) with a high resolution Fourier transform spectrometer. Isobutane absorption cross sections were determined for six temperatures from 295 K to 739 K. These data may be useful for simulations of hot Jupiter exoplanets and brown dwarfs. Integrated cross sections were compared with adjusted cross section data from the Pacific Northwest National Laboratory (PNNL) database.
