In this framework, the geometrical conformational analysis of the title molecule pointed out the most stable conformation with the energy of -818.732369 Hartree and the dipole moment of 5.431104 Debye. Additionally, the vibrational frequencies were calculated and compared with experimental values and a good agreement between the measured and calculated values for the molecule 1-(o-Tolyl)thiourea were obtained. Furthermore, some thermodynamic parameters of the title molecule were calculated at the mention level of the theory. (C) 2020 Elsevier B.V.
