dc.description.abstractModerate-resolution spectra $(0.112 cm^{-1})$ (MRS) and high-resolution spectra $(0.002 - 0.003 cm^{-1})$ (HRS) of anhydrous nitric acid have been recorded between about $820 cm^{-1}$ and $3600 cm^{-1}$. The MRS were recorded using a Bruker IFS 66V FTIR for at least five pressure burdens at each of three temperatures (278, 298, 323 K) in a temperature regulated cell with $BaF_{2}$ windows. Nominal pathlength was 20 cm. The static fills of anhydrous nitric acid samples were back filled with nitrogen to a total pressure of $760 \pm 5$ Torr. Small absorbances from $H_{2}O, CO_{2}, NO, NO_{2}$ and $N_{2}O$ were accounted for and subtracted from the spectra. The corrected spectra were used to obtain integrated band absorption coefficients as well as a compilation of absorption coefficients tabulated at $0.056 cm^{-1}$ intervals. Within an experimental error of about two percent, the integrated band intensities are independent of temperature and in good agreement with results obtained by $Giver et al.^{a}$ HRS of nitric acid were recorded with a Bruker IFS 120HR FTIR using a flow of neat anhydrous nitric acid through a temperature regulated (296 K) cell with a nominal pathlength of 10 cm and $BaF_{2}$ windows. At least four pressure burdens were measured for each spectral region. Progress will be reported on the line by line analysis of the HRS for intensities in the $845 - 945 cm^{-1}(\nu_{5}, 2\nu_{9}), 1270 - 1370 cm^{-1}(\nu_{3}, \nu_{4})$, and $1660 - 1760 cm^{-1}(\nu_{2})$ spectral regions.en_US
