Abstract
By means of FT-IR and subtraction techniques the absorption spectra of Poly A film have been studied systematically in the 4000 to 800 cm-1 region at 25 0C as a function of relative humidities (from 0% to 100%) approached by static equilibrium. According to the frequency and intensity changes of infrared spectra it proves that the hydration of Poly A has happened mainly on the -NH2 group of base, -P02 group and ribose ring. The largest frequency shift is observed on the -NH2 band and the strongest variation in intensity is on the -NH2 band, ribose-phosphate main chain vibration and -P02 symmetric stretching vibration. The spectra of water molecule also vary obviously and split into multiple peaks during hydration.
