Consider the following statement(s) in the context of NO and CO ligands

A. In the bent mode, NO donates three electrons to the metal center.

B. In the IR spectrum, the v_NO for the bent nitrosyl ligand typically lies between 1525 and 1690 cm^-1.

C. The HOMO of NO and CO are π^* and σ orbitals, respectively.

The correct statement (s) is/are
