2.3 Spectroscopic study:The characterization of synthesized compounds was done by IR NMR and, mass spectral data.IR spectra were scanned on SHIMADZU FTIR-8400 Spectrophotometer in frequency range of 4000400 cm-1 by KBr - DRS Method.1H NMR spectral was recorded in DMSO with tetramethylsilane (TMS) as the internal standard at 400 MHz on a BRUKER AVANCE. II - 400 spectrophotometer.The chemical shifts are reported as parts per million (PPM).The mass spectra of synthesized compounds were recorded by GCMS-SHIMADZU-QP2010.
