Collisional Effects on Molecular Spectra

Gas phase molecular spectroscopy is a powerful tool for obtaining information on the geometry and internal structure of isolated molecules as well as on the interactions that they undergo. It enables the study of fundamental parameters and processes and is also used for the sounding of gas media through optical techniques. Historically, gas phase molecular spectroscopy has faced challenges, due to the considerable improvement of experimental techniques and the increasing demand for accuracy and scope of remote sensing applications.
