In this study, the effect of functional groups of 1,4 butynediol
(BOZ), 2-butyne-monopropoxylate (BMP), and butynediol ethoxylate (BEO)
molecules in nickel electroplating bath was investigated by using
electrochemical and computational methods 
and compared. The initial potential of
nickel electroplating shifts the negative area in the presence of
organic additive according to the oxygen number in the structure. The
shift increased in the order of BOZ, BMP, and BEO. Dipol moment and
HOMO-LUMO energies obtained from theoretical calculations explained
the reason of the negative area shift of BEO molecule, which
consequently led to more bright surface even at lower concentrations
and supports the experimental results.
