2. Experimental
The solid phase FT-IR spectrum was recorded in the region
4000e400 cm
1
in evacuation mode on Bruker IFS 66 V spectrometer
using a KBr pellet technique with 4.0 cm
1
resolution. The
FT-Raman spectrum was recorded using 1064 nm line of Nd: YAG
laser as the excitation wavelength in the region 4000e50 cm
on
Bruker IFS 66V spectrometer equipped with FRA 106 Raman
module was used as an accessory. The UV visible spectral measurements
were carried out in the range 200e800 nm is using a
Varian Cary 5E-UV-NIR spectrophotometer. NMR chemical shifts
were recorded in BRUKER 400 MHZ NMR spectrometer and solvent
used for the sample DMSO. The spectral measurements were carried
out at the Sophisticated Analysis Instrumentation Facility
(SAIF), IIT Madras, India.
