“…Molecular Electrostatic Potential (MEP) and frontier molecular orbitals (HOMO and LUMO) profiles were plotted using the optimized structures. 41 The electronic molecular properties including HOMO–LUMO energy gap ( E g ), electronegativity ( χ ), chemical potential ( μ ), electron affinity ( A , which is defined as − E LUMO ), ionization potential ( I , which is defined as − E HOMO ), and global hardness ( η ) of studied species were calculated based on the following equations: 42,43 E g = E HOMO − E LUMO χ = − μ = −( A + I )/2 η = ( I − A )/2…”
