The spectra were obtained using potassium bromide pellet technique. Potassium bromide (AR grade) was dried under vacuum at 100 ◦C for 48 h and100 mg of KBr with 1 mg of sample was taken to prepare KBr pellet. The spectra were plotted as intensity versus wave number. NMR spectrum was recorded in a Bruker Avance III with a 5 mm probe. The sample was dried in vacuum and dissolved in 0.7 ml of D2O (99.96) at a concentration of 10 and 30 mg/ml for 1H NMR and 13C NMR respectively.
