Abstract

Spectra of the v₇ band of ethylene were recorded using a tunable diode laser spectrometer and their linewidths were measured. Spectra acquired at pressures between 10 and 50 milliTorr and in a 45 cm cell are analyzed. Temperature is also accurately recorded. Line intensities are retrieved from the observed line widths. A broad band spectrum acquired at the Kitt Peak National Observatory on a Fourier transform spectrometer was also studied. TDL line intensities are used to calibrate the FTS data , and CO₂ lines present in the FTS spectrum are used to calibrate line positions. A corrected pressure is determined and a series of line strengths from the Fourier transform spectra is reported
