High-resolution absorption cross sections of C${}_2$H${}_6$ at elevated temperatures

Abstract

Infrared absorption cross sections near 3.3 $\mu$m have been obtained for ethane, C${}_2$H${}_6$. These were acquired at elevated temperatures (up to 773 K) using a Fourier transform infrared spectrometer and tube furnace with a resolution of 0.005 cm${}^{-1}$. The integrated absorption was calibrated using composite infrared spectra taken from the Pacific Northwest National Laboratory (PNNL). These new measurements are the first high-resolution infrared C${}_2$H${}_6$ cross sections at elevated temperatures.
