The IR spectroscopy is the most powerful and useful technique adopted by all the chemists to analyze, confirm and elucidate the structure of compounds and to identify the functional groups present in them.
Fig. 2 shows the FT-IR spectra of the as synthesized samples recorded using a schimazdu-IR affinity1 spectrophotometer in the range of 4000 cm1 –400 cm1 .
The broad peaks around 3425 cm1 were corresponding to the O–H stretching mode.
The peaks at 425–520 cm1 correspond to the Zn–O stretching mode (A1 – 485 cm1 , A2 – 425 cm1 and A3 – 516.7 cm1 ) of vibration. The broad bands at around 500 cm1 due to the superposition of two or three separate bands in all the samples indicate the high orientation of the rods [17].
