Abstract:

Absorption coefficients were measured for ethylene in the 9 micron and 10 micron range with an optoacoustic spectrophone. Pressure dependency in the 10P CO2 range was studied for various concentrations of ethylene. Comparisons of the data to other measurements of both atmospheric and pressure dependent absorption coefficients were also made, and a method for relating ethylene pressure dependency data on absorption to molecular structure was examined. Typical discrepancies between up to six independent measurements of ethylene absorption were 38.1 percent at the 10 micron R20 line, 4.4 percent at the 10 micron P18 line, and 18.5 percent at the 10 micron P26 laser line.
