Using nitrogen to broaden the rotational lines, the band strengths have been measured at 296K under conditions for which the rotational structure is smeared out. Using these results for the absolute intensities of the bands and the already published rotational analysis of these bands, we have made a comparison of a line-by-line calculation with our lower pressure spectra of the $C_{2}H_{4}$ nitrogen-broadened lines at temperatures of 150K, 200K, and 296K. en_US dc.format.extent 79433 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title A STUDY OF THE THERMAL INFRARED BANDS OF ETHYLENE AT LOW TEMPERATURES en_US dc.type article en_US
