INTRODUCTION. Considering the interesting bonding nature and the importance in some biochemical processes chemists and biochemists recently have made quite extensive investigations on the synthesis, structure and spectra of the sulfur-donor ligand compounds. We have performed determination of the molecular structures and the assignments of the vibrational spectra of three compounds, namely H_2NCSSCH_3, H_2NCOSCH_3 and H_2NCSOCH_3~[1,2], and obtained the INTRODUCTION.
