Abstract

\begin{wrapfigure}{l}{0pt} \includegraphics[scale=0.3]{Q-Columbus.eps} \end{wrapfigure} We present the first (preliminary) investigation of the $\nu_1$ band (OH stretching mode) of Nitric acid (HNO$_3$) centered at 3551.766~cm$^{-1}$ using high resolution Fourier transform spectra. These spectra were recorded in the 2.5 $\mu$m to 3.23 $\mu$m spectral regions on the spectrometer located on the AILES beamline of the SOLEIL synchrotron. Because of the large value of the Doppler linewidth (about 0.003~cm$^{-1}$) in the 2.8 $\mu$m region at 220~K or 296~K), the analysis was very complex and often uncertain and dubious. Furthermore, the $\nu_1$ band is severely affected by numerous perturbations. Among these ones, unexpected line splittings were observed during all the analyses. Finally we have generated a preliminary list of "reasonable" line positions and intensities for the $\nu_1$ band and of the $\nu_1$+$\nu_9$-$\nu_9$ bands and $\nu_1$+$\nu_7$-$\nu_7$ hot bands.
