A constant HF pressure of 2.15 cm. of mercury was used, and to this was added $25, 50, 75,$ and 100 psi of $CO_{2}$. For each line the shift was found to be proportional to the $CO_{2}$ pressure. In the R branch of the band, the lines with $|m|$ equal to one or two were shifted to higher frequencies and the lines with $|m|$ greater than two were shifted to lower frequencies. In the P branch, for corresponding values of $|m|$, the lines were shifted in the opposite directions. However, the effect with $|m|$ greater than four in the P branch was not ascertained, due to the presence of a strong $CO_{2}$ absorption band. en_US dc.format.extent 130799 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title LINE SHIFTS OF HF DUE TO $CO_{2}$ en_US dc.type article en_US
