THE THEORETICAL STUDIES OF MOLECULAR ORBITALS AND THERMODYNAMIC PROPERTIES OF ANTIFUNGAL DRUG
AbstractIn this work, the molecular structure optimization, electronic properties like local chemical reactivity descriptors (Fukui function analysis for reactive site prediction), and thermodynamic properties (Heat capacity, entropy, zero points vibrational energy, thermal energy, translational, rotational and vibrational energy) of antifungal drugs were theoretically computed. In this work also, electronic structure, frontier molecular orbital energies (HOMO-LUMO gap for the chemical activity of drug), molecular electrostatic potential (useful for recognizing electrophilic and nucleophilic attack) and mulliken charge has been carried out. Atomic charges dipole moment, molecular polarizability, electronic parameter, and refractivity of molecular systems were calculated by the DFT method. The reactive site prediction and hydrogen bond interaction analysis was determined by using the Fukui function analysis. In this study, DFT/B3LYP/6-31+G and DFT/CAM-B3LYP/6-31+G (d, p) methods were used.
