Density Functional Theory (DFT) was used to optimize the molecule at the STO-3G basis set to calculate the highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) energy levels of the frontier orbitals of acrylic acid. The energy gap between HOMO-LUMO orbitals was calculated to be 5.545 eV. This demonstrated that the energy gap reflects the chemical activity of the molecule. The compound was characterized by UV-Visible, Nuclear Magnetic Resonance (NMR), and Fourier Transform Infrared (FT-IR) spectroscopy methods.eninfo:eu-repo/semantics/openAccessKimyaAnalitikNMRFT-IRUV-VisHOMO and LUMOAcrylic AcidTheoretical Investigation of the Chemical Reactivity of Acrylic Acid Molecules: A DFT Study with UV-Vis, NMR, and FT-IR Spectroscopy Using STO-3G Basis SetArticle10.53433/yyufbed.13507552924384461260119
