We present our recent experimental results on self- and air broadening in the $\nu_{3}$ bands of $SO_{2}$ and $NO_{2}$, obtained with a TDL-spectrometer with pulse driven lasers. In the case of strong line overlapping the spectra were treated with a Fourier analysis technique to derive the broadening coefficients. For $SO_{2}$ the first experimental data for the rotational quantum number dependence of the broadening coefficients are reported. The results are discussed with respect to the theoretical data (calculated by Tejwani applying the Anderson-Tsao-Curnutte theory) and to their application for the modelling of the pressure dependence of the spectra. en_US dc.format.extent 107332 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title Line Broadening in the $\nu_{3}$ Bands of $SO_{2}$ and $NO_{2}$ Studied with Tunable Diode Laser Spectroscopy en_US dc.type article en_US
