FT-IR, FT-Raman spectra and other molecular properties of 2,4- dichlorobenzonitrile: a interpretation by a DFT study.

FT-IR and FT-Raman spectra of 2,4-dichlorobenzonitrile at room temperature have been recorded in the regions 200-3500cm(-)(1) and 0-3400cm(-)(1), respectively. The observed vibrational bands were analyzed and assigned to different normal modes of the molecule according to the Wilson's notation. Density functional calculations were performed to support our frequency assignments.
