Abstract

In view of the application of light-extinction techniques for fuel-specie-concentration measurements in combustion systems, the vapor-absorption coefficient of several hydrocarbon species at the 3.39-μm He-Ne laser transition has been measured. The hydrocarbon species include paraffins, olefins, and aromatics. Results are included for total pressure over the range of approximately 200-650 Torr at 295 K with air as the buffer gas. Observations are made regarding the difference in the absorption coefficient within and between hydrocarbon classifications.
