In optical Fe II emitters, the redward asymmetry of Hβ is partly due to a blend of Fe II lines from multiplets 42, 36, and 25. A new attempt is made to quantify the contribution of Fe II using the results of theoretical work on the formation of the Fe II lines in AGN. A relation is found between this contribution and the easily observed Fe II blend around λ4750. It is argued that the stronger the Fe II emitter, the larger the contribution of multiplets 36 and 25. A comparison with previous work shows that when the Fe II contribution is restricted to the observed intensity of multiplet 42, it is often underestimated and that in Fe II emitters the Hβ asymmetry is often overestimated.
