With the modern technology and availability of spectrometer systems, it is possible to provide more accurate and new parameters to the spectroscopic databases. Accordingly, three spectroscopic studies were carried out in this thesis. The first study is intended to find the suitable line-shape models that can reproduce C2H2-N2 spectra best as well as retrieve reliable parameters, which are very useful for spectroscopic studies. The second project of oxygen A-band spectra is dedicated to retrieving a new parameter, called the speed-dependent parameter. The main goal of the third study is to obtain a better ground state line list of 15NH3, which has never been studied as extensively as in this thesis. Performing the acetylene study will improve the use of line-shape profiles based on the spectral pressure regions. The new speed-dependent parameter and extended (439) lines of 15NH3 spectroscopic results will progress the retrievals of atmospheric spectra and enrich spectroscopic databases.
