2.4.3. Infrared spectroscopy
All the FTIR spectra were recorded with a PERKIN ELMER Spec-trum One FTIR spectrometer operating in Fourier Transformed and
interfaced with a processor having the software Spectrum version
3.02.01. Baseline and smooth correction were performed after 16
scans. The samples (about 1 mg) were prepared by using anhy-drous potassium bromide – spectroscopy grade (KBr 99.4%) pur-chased from Across Organics.
