The high resolution $(0.002 cm^{-1})$ FTIR absorption data of this band have been analyzed by taking into account the Coriolis interaction with the $\nu_{8} (1435.6 cm^{-1})$ level. A strong intensity perturbation was observed, which enhances the intensity of the $\nu_{2}$ band. More than $1000 (J^{\prime\prime}=40. Ka^{\prime\prime}=20)$ transitions were assigned in the $\nu_{2}$ band and a simultaneous least squares fit of the data of the $\nu_{2}$ and the $\nu_{8}$ bands was carried out. The molecular parameters and the interaction parameters obtained from the fit, satisfactorily reproduce the observed relative inctensities of the spectrum. By simulating the spectrum, we could also determine the relative sign of the transition dipole moments for $\nu_{2} \leftarrow 0$ and $\nu_{8} \leftarrow 0$ transitions. en_US dc.format.extent 83615 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title HIGH RESOLUTION FTIR STUDIES OF THE $\nu_{2}$ BAND OF $CH_{2}F_{2}$ en_US dc.type article en_US
