Characterization (FT-Raman, FT-II Spectra) of 3.5-Dimethoxybenzaldehyde C9H10O3 and Compared with Density Functional Theory (DFT)

The FT-IR and FT-Raman spectra of 3.5- dimethoxybenzaldehyde C9H10O3 molecule have been recorded in the range of 4000–400 cm^-1 and 3500–50 cm^-1 respectively. The molecular geometry and vibrational frequencies in the ground state are calculated using the DFT/B3LYP method with 6- 311G++(d,p) basis sets and assuming CS symmetry. The computed values of frequencies are scaled using a suitable scale factor to yield good coherence with the observed values.
