The infrared and Raman spectra of the zinc (II) halide complexes of 4-Ap have been recorded between 400-4000 cm-1 and 5-3500 cm-1 regions, respectively. The analysis of the FT-IR and FT-Raman spectra indicates that some structure-spectra correlations. For a given series of isomorphous complexes, the sum of the differences between the values of the vibrational modes of uncoordinated 4-Ap was found to increase in order of second ionization potentials of metal. The molecular geometry and vibrational frequencies of the zinc (II) halide complexes of 4-Ap in the ground state have been calculated by using the Density Functional Method (B3LYP) with LANL2DZ and SDD as basis sets. A complete assignment of the fundamentals was proposed based on the total energy distribution (TED) calculation. <br> </p>}, number={4}, publisher={Gazi University}
