The spectrochemical series was first proposed in 1938 based on the results of absorption spectra of cobalt complexes. A partial spectrochemical series listing of ligands from small Δ to large Δ is given below. (For a table, see the ligand page.) I < Br < S < SCN (S–bonded) < Cl < NO3 < N3 < F < OH < C2O4 < H2O < NCS (N–bonded) < … WebH2O is undoubtedly a weak field ligand. However while dealing with complexes having central atom in higher oxidation state or of 2nd and 3rd transition series the nuclear pull of the central atom changes the scenario. In simple words it can be said that H2O behaves as a strong field ligand with Co+3 and ions of 2nd and 3rd transition series.
