Özet
In this research, Quantum-mechanical calculations were performed at the HF method with the STO-3G, 6-31G, 6-31G∗, 6-31G∗∗, 6-31+G∗∗ and 6-31++G∗∗ basis sets and at the BLYP and B3LYP method with the STO-3G, 6-31G, 6-31G∗, 6-31G∗∗, 6-31+G∗∗ and 6-31++G∗∗ basis sets in the gas phase at 298 temperature. According to these theoretical results of IR, we extracted thermo chemical parameter such as Energy (ΔE Kcal/mol). The optimizations of (2-fluoro-2-isothiocyanatoethyl)benzene, (2-chloro-2 isothiocyanatoethyl)benzene, (2-bromo-2- isothiocyanatoethyl)benzene, (2 isothiocyanatopropyl)benzene, (2-isothiocyanato Butyl)benzene and (1-isothiocyanatoethane-1,2-diyl)di benzene are carried out including exchange and correlation contributions using BLYP and B3LYP. Also, nuclear shielding parameters of Compounds, such as chemical shift isotropic value (∗iso) and the anisotropy shielding (∗aniso, Δ∗), charge, η12 and Dipole moment have been taken into account using GIAO method at the B3LYP method with the 6-31++G∗∗ basis set in the gas phase.
