J Appl Spectrosc 86, 975–985 (2020).00219037https://doi.org/10.1007/s10812-020-00926-2https://hdl.handle.net/11413/8014The structure and vibrational calculations of 5-chlorouracil (5-ClU) and its most stable dimer have been analyzed using the DFT method with B3LYP/6-31++G(d,p) and wb97xd/6-31++G(d,p), respectively. Vibrational calculations of the monomeric and dimeric forms were performed using both harmonic and anharmonic oscillator approximations with the same basis sets. A complete vibrational analysis of the molecule has been performed by combining experimental Raman, FT-IR spectral data and quantum chemical calculations. In addition, the DNA docking analysis of 5-ClU molecule was performed. A 5-ClU molecule binds to the active site of DNA by hydrogen bonding interactions. The results show that the docked ligand formed a stable complex with DNA with binding affi nity of –5.3 kcal/mol.eninfo:eu-repo/semantics/restrictedAccess5-ChlorouracilDimeric StructureMolecular DockingDensity Functional TheoryVibrational SpectroscopyArticle2-s2.0-85078267504
