“…The IR spectrum of the ligand system contains intense CQN absorption bands from the pyridine ring at 1468-1485 cm À1 and CQN from azomethine fragments at 1695-1703 cm À1 depending on substitutes R. These frequencies are well matched with the experimental values. 39,40 In the Ru(II) complexes, CQN het undergoes a low-frequency shift by 20-90 cm À1 with increasing intensity. The azomethine bonds CQN have the same trend with more significant shifts by 100-120 cm À1 .…”
