Özet
The Fourier transform infrared, laser-Raman, proton and carbon-13 nuclear magnetic resonance chemical shifts, and Ultraviolet (UV)-Visible spectra of the 5-(4-pyridyl)-1H-1,2,4-triazole-3-thiol molecule have been experimentally recorded. The molecular geometric structure analysis, vibrational frequencies, electronic absorption spectroscopy, frontier molecular orbital energies, and molecular electrostatic potential of the 5-(4-pyridyl)-1H-1,2,4-triazole-3-thiol molecule have been calculated by using density functional theory calculations with the 6-311++G(d,p) basis set in the ground state, for the first time. Additionally, natural bond orbitals and non-linear optical properties of the 5-(4-pyridyl)-1H-1,2,4-triazole-3-thiol molecule have been theoretically investigated by using the mentioned level. The obtained results show that the theoretical values are in good agreement with experimental data.
