The observed experimental FT-IR and FT-Raman spectra are shown
in Figs. 1 and 2. The theoretically predicted IR spectra calculations
at HF/6-311G(d,p) and B3LYP/6-311G(d,p)methods are shown
in Fig. 3. The theoretically predicted Raman spectra at B3LYP/6-
311G(d,p) (best level) of calculation is also shown in Fig. 4. The
spectral measurements were carried out at Central Electro Chemical
Research Institute (CECRI) Karaikudi (Tamil Nadu), India.
