Calculations are presented of vibrational absorption spectra for PCE, TCE, DCE and VC molecules using density function theory (DFT). These ground water contaminants are among the most widely spread carcinogens in the environment of industrial countries. DFT calculated absorption spectra of isolated molecules represent quantitative estimates that can be correlated with additional information obtained from laboratory measurements. The chlorohydrocarbons, whose spectra are calculated, are characterized by an interconnected equilibrium network. The simultaneous knowledge of the spectrum of each molecule within this network will be useful for detection and monitoring of the water contaminants. The DFT software GAUSSIAN was used for the calculations of the infrared (IR) spectra presented here.
