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.
