Abstract

The solvent effect on the title compound was studied by examining changes in the positions of IR bands belonging to the NH and CO bonds and in the dipole moments in benzene and dioxane solutions. The results are discussed in terms of intramolecular hydrogen bonding and spatial arrangement of the CONHCSNH grouping.

Keywords: IR spectra; Hydrogen bonds; Solvent effect; Dipole moment.
