FT-IR parameters for spectral acquisition
All IR spectra were recorded on 5700-FTIR spectrometer of
Thermo Nicolet with KBr accessory and deuterated triglycine
sulfate (DTGS) detector. This instrument was operated with OMNIC
(Thermo Nicolet) version 7.3. The resolution was optimized at
4 cm1 by averaging 32 scans in Mid IR region of 4000–400 cm1
and priority was not to lose any spectral information. The fresh
background spectrum was recorded from KBr pellet before each
FTIR run for standard and sample. All the spectra were recorded
in KBr pellet form under same optimized conditions
