摘要
Vibrational absorption spectra are presented for isolated molecules of some common polyfluorides, present in food and pharmaceutical production, which are calculated using density function theory (DFT). This study further demonstrates using DFT for characterizing IR-spectral features of substances within the environment. DFT calculated absorption spectra of isolated molecules represent quantitative estimates that can be correlated with additional information obtained from laboratory measurements. The DFT software GAUSSIAN was used for calculating the infrared (IR) spectra presented here. DFT calculated spectra can be used to construct templates, which are for spectral-feature comparison, and thus detection of spectral-signature features associated with target materials.
