Abstract
MO calculations were performed on the different conformers of thiobenzophenone and on the planar conformer of a number of its derivatives using the INDO-CI procedures. A nonplanar conformer with an angle of 15° between the planes of benzene rings was predicted for thiobenzophenone. Dipole moment and charge density were calculated and correlated to the reactivity of the studied molecules. A Gaussian analysis was performed on the spectra of the studied compounds, results compared satisfactorily with the results of MO calculations.
