In the density range 60-300 Amagat units the integrated intensities showed a weak linear dependence on the foreign gas density. Extrapolation Lo zero foreign gab density gave values for the absolute intensities of the $\nu_{3}, \nu_{1}$ and $\nu_{2}$ bands. A detailed examination of the errors inherent in this experimental method was made. In this density range the band profiles could be fitted with computed profiles assuming suitably broadened rotational lines; pressure broadening coefficients for the various foreign gases were obtained from this procedure. The high pressure data yielded three interesting results: a redistribution of the intensity within the bands occurred, the frequencies of the maximum absorption increased, and the integrated intensity of the $\nu_{3}$ decreased while that of the $\nu_{4}$ band increased. These results will be discussed.” en_US dc.format.extent 92256 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title EFFECT OF FOREIGN GASES AT HIGH PRESSURES ON THE INFRARED BANDS OF $CH_{4}$ en_US dc.type article en_US
