High resolution absorption cross sections for propylene in the 3 µm region at high temperatures

High resolution infrared spectra in the 3 µm region for propylene (C3H6) were recorded at temperatures up to 700 K. Measurements were taken using a Fourier transform infrared spectrometer at a resolution of 0.005 cm−1 using a quartz cell inside a tube furnace. Calculated cross sections were calibrated against composite spectra from the Pacific Northwest National Laboratory. These cross sections are provided with this work and will find use in remote sensing and combustion monitoring.
