UV Vis spectroscopy is used in providing the information about electronic bond state of atoms but it does not provide any information about the directionality of the bond. The information of directionality becomes critical especially in case of polymers to provide a complete understanding of polymerization reactions and the molecular structure of the species involved. The use of FTIR as a characterization technique hence comes into picture. It is used to determine the spatial quantization of bond structure. The vibrational state of bond is characterized by using FTIR

Ultraviolet Radiation deals with a totally different set of wavelengths and energy output than Infrared does. Also Infrared and Ultraviolet are on opposite ends in the visible light spectrum.
