The physicochemical attributes of inhibitor → metal & metal alloys nanosheet can be one of the fundamental factors for recognizing determining and selecting the Langmuir adsorption through IR, NMR, NQR, NBO, UV--VIS, HOMO/LUMO, and charge distribution and other quantum attributes. Then, the fluctuation of occupancy of natural bond orbitals has been estimated for pyridine → Al--Al, pyridine → Al--Mg, pyridine → Al--Ga, pyridine → Al--Si; 2-picoline → Al--Al, 2-picoline → Al--Mg, 2-picoline → Al--Ga, 2-picoline → Al--Si; 3-picoline → Al--Al, 3-picoline → Al--Mg, 3-picoline → Al--Ga, 3-picoline → Al--Si, 4-picoline → Al--Al, 4-picoline → Al--Mg, 4-picoline → Al--Ga, 4-picoline → Al--Si, and 2,4-lutidine → Al--Al, 2,4-lutidine → Al--Mg, 2,4-lutidine → Al--Ga, and 2,4-lutidine → Al--Si through the Langmuir adsorption process due to concerning the nitrogen atom in the ... |
