Abstract: To understand the changes occurring in the structure upon deuteration, a series of hydrogenous atactic polystyrene with different selectively deuterated variants was analyzed by Fourier Transform Infrared (FTIR) Spectroscopy. It was observed that the spectra were sensitive to a modification by deuteration of adjacent functional groups. These results also clearly show that the vibrational bands depend on the strength of the bonds and the masses of the atoms involved in the particular vibrational mode. Also using the selectively deuterated functional groups allowed to uniquely assigning peaks, which were not assigned previously to chain or ring vibration.
