Abstract  The corrosion-inhibiting efficiencies of 5 aliphati c amines on Fe electrode in H2SO4 solution have been determined with weight- loss method.The molecular geometries of the aliphatic amines have been optimized ,and their structure parameters were obtained by means of MNDO method,respective ly.Linear regression showed good correlation between the inhibition efficiencies and the average values of the N-atom net charge for non-protonated and protonat ed molecules,and EHOMO,+ and ELUMO,+ of protonated molecules ,respectively.
