Structural and spectral studies on 3-(6-benzoyl-5-chloro-2-benzoxazolinon-3-yl) propanoic acid

The molecular geometry and vibrational frequencies of the 3-(6-benzoyl-5-chloro-2-benzoxazolinon-3-yl) propanoic acid in the ground state has been calculated using the Hartree-Fock and density functional using Becke's three-parameter hybrid method with the Lee, Yang, and Parr correlation functional (B3LYP) methods with 6-31G(d) basis set. The theoretical vibrational spectra of the title compound were interpreted by means of potential energy distributions (PEDs) using VEDA 4 program. The calculated geometrical parameters and harmonic vibrations are in a very good agreement with experimental data. With the aid of this modern technique we were able to complete the assignment of the vibrational spectra of the title compound.
