Abstract
The corrosion inhibition of mild steel in 1 M HCl by three substituted quinoxalinones namely quinoxalin21Hone Q1 6methylquinoxalin21Hone Q2 and 6nitroquinoxalin21Hone Q3 was investigated using density functional approach B3LYP/631G calculations The calculated quantum chemical parameters are the highest occupied molecular orbital energy E HOMO lowest unoccupied molecular orbital energy E LUMO energy gap ΔE dipole moment μ electronegativity χ electron affinity A global hardness η softness σ ionization potential I fraction of electrons transferred ΔN global electrophilicity ω polarisability α and total energy All calculations have been performed by considering DFT using the GAUSSIAN03 W suite of programs The obtained parameters are calculated and discussed
