| Abstract: | The molecular geometry optimization and frequency calculation of two isomer molecules have been carried out using density functional theory at the level of B3LYP/6-311＋G＊.The results show that the most stable isomer,whose amide group and thiazole ring are actually coplanar（and the same is true of the benzene ring and the Triazole Ring）,is made of two conjugate planes,with the dihedral angle of about 30°.The spectra and thermodynamic properties are calculated,which in turn produces the IR,Raman spectra and the relational expression of thermodynamic properties with temperature. |
