Abstract

Conventional I.R. spectroscopy yields for ethylene a very strong absorption band (υ7) in the region of emission of the CO2 laser. High resolution spectroscopy shows however [1] that most vibro- rotational transitions do not coincide closely with the laser lines, so that strong absorption should not be expected. Nevertheless all CO2 lines may excite ethylene even at low pressure.
