Rotationally Resolved Infrared Spectroscopy to Determine the Transition Parameters of the nu9 Band of Ethane
EMSL Project ID
32590
Abstract
The purpose of this project and associated subcontract is to perform rotationally resolved spectroscopic measurements of ethane (12CH312CH3) in the 820 cm-1 region corresponding to the nu9 fundamental band. The measured spectra will be used to determine infrared absorption line strengths, self- and nitrogen-broadening, and line shift parameters for the ro-vibrational transitions in the aforementioned band. Dr. Thomas A. Blake of PNNL will make the measurements using the Bruker IFS120HR spectrometer located in EMSL Room 1130 and will deliver the data to Dr. Curtis Rinsland of NASA Langley. Dr. Rinsland will further reduce and analyze the data.
