Özet
The density functional theory (DFT) at the B3LYP/6‐31G (d,p) and B3LYP/6‐311G(d,p) basis set levels and ab initio calculations using the HF/6‐31G (d,p) and HF/6‐311G(d,p) methods were performed on four rhodanine azosulpha drugs (namely 5‐sulfadiazineazo‐3‐phenyl‐2‐thioxo‐4‐thiazolidinone, 5‐ sulfamethazineazo‐3‐phenyl‐2‐thioxo‐4‐thiazolidinone, 5‐sulfadimethoxineazo‐3‐phenyl‐2‐thioxo‐ 4‐thiazolidinone, and 5‐sulfamethoxazoleazo‐3‐phenyl‐2‐thioxo‐4‐thiazolidinone) used as corrosion inhibitors for mild steel in acidic medium to determine the relationship between the molecular structure of the rhodanine azosulpha drugs and inhibition efficiency(%IE). The quantum chemical parameters/descriptors, namely, EHOMO (highest occupied molecular orbital energy), ELUMO (lowest unoccupied molecular orbital energy), the energy difference (ΔE) between EHOMO and ELUMO, dipole moment (μ …
