The report describes a thermally initiated F2H2 flow tube reactor experimental program to provide clearly defined experimental results via emission spectroscopy diagnostics on vibrational population levels attained in the cw H2F2 chain reaction for comparison with theory. Highly dilute, subsonic, near room temperature reaction conditions in the 1-10 torr pressure region have been studied which result in development of the chain over flow tube distances of about 1 meter, much larger than mixing length. An examination of the dominant kinetics was conducted via the accumulation of spectral and uv data over a range of key experimental parameters including distance from the H2 injector, x H2 flow F2 flow pressure dissociator temperature, and O2 additive flow. Overtone spectra were obtained. The experimental results from the flow tube on high lying vibrational population distributions ovserved at 5 torr have been compared with predictions of the 1-D scheduled mixing analytical model in a manner which attempts to identify potential key areas of kinetic uncertainty with the chain.
