In this study, it was obtained the IR spectrum, fingerprint area, vibrational frequances, bond length and bond angle values from geometric parameters of 4-amino-1Hbenzo[4,5]imidazo[1,2-α]pyrimidin-2-one molecule’s by Gaussian 09 programme. In the calculation, it was used HF/3-21G, 6-31G(d), 6-31G(d,p), 6-311G(d) ve B3LYP/3-21G, 6- 31G(d), 6-31G(d,p), 6-311G(d) methods. 4-amino-1H-benzo[4,5]imidazo[1,2-α]pyrimidin-2-one’s empirical vibrational frequancies and our obtained values in this study were taken together. It was seen that the
empirical and theoreticall values were in good agreement. With this study, 4-amino-1Hbenzo[4,5]imidazo[1,2-α]pyrimidin-2-one complex’s chemistry structure used in dye endustry was determinated . In advance, by studing theoretically our complex and similar complexes, we aim to gain time for the empirical studies and in this way, to support the endustry as scientific.
