Optoacoustic Spectroscopy of C2H4 at the 9 micrometers and 10 micrometers C12O2(16) Laser Wavelengths.
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 R(20) line, 4.4 percent at the 10 micron P(18) line, and 18.5 percent at the 10 micron P(26) laser line.
