As discussed in

Strong Field Ligand -

These are the ligands which pair the electron in inner d-orbital and makes required d-orbitals empty/available. 

- wherein

For example: CO, CN etc

 

 and, 

 

Spectrochemical series -

I^{-} < Br^{-}< SCN^{-}< Cl^{-}< S^{2^{-}}< F^{-}< OH^{-}< C_{2}O_{4}^{2-}< H_{2}O< EDTA< NH_{3}< en< Cn^{-}< CO

-

 

 The order of spectrochemical series is 

I^{-}<Br^{-}<SCN^{-}<Cl^{-}<S^{2-}<F^{-}<OH^{-}<C_{2}O_{4}^{2-}<H_{2}O<EDTA^{4-}<NH_{3}<en<CN^{-}<CO
