Özet

The mid-IR spectrum of Oxazole (Oxa) is recorded. This spectrum is interpreted with the help of B3LYP/6-311++G(d,p) calculations and potential energy distribution (PED) analysis. The experimental spectrum is concordant with the theoretical data. Geometrical parameters and the atomic charges are also theoretically obtained and presented. Solvent effects on the geometrical parameters, vibrational frequencies, and electronic properties of Oxa are analyzed theoretically in chloroform, ethanol, and water. Besides, hydrogen bonded Oxa center dot center dot center dot(H2O)(n) (n = 1, 2 10) complexes are investigated within the PCM solvation model. It is found that the interaction energies in Ox center dot center dot center dot(H2O)(n) complexes are influenced by the number of water molecules, and by the arrangement of water molecules.
