Laser Raman and IR spectra and force fields for 2,4-dichlorobenzonitrile

Raman spectrum of 2,4-dichlorobenzonitrile (2,4-DCBN) in powder form has be en recorded in the region 50-4000 cm(-1) on a Jasco K-500 Raman spectrophot ometer using the 488.0 nm radiation from an argon laser. FTIR spectra in th e region 200-4000 cm(-1) have been recorded in KBr pellet and nujol mull on a Nicolet DX spectrometer. Using the observed Raman and IR frequencies, no rmal co-ordinate analysis has been carried out to support the vibrational a nalysis and to determine the planar and non-planar force fields.
