• Dimethyl sulfide and dimethyl sulfide-d<SUB>1</SUB> were prepared, and their infrared spectra were measured in the gaseous and liquid states. The Raman spectra were measured in the liquid state. The assignments of their spectra were made. On these assigned frequencies, two sets of modified Urey-Bradley force constants and a set of local symmetry force constants were determined by a least-squares technique. The obtained force constants were then transferred to the treatment of the vibrational frequencies of dimethyl sulfide-d<SUB>3</SUB>. The centrifugal distortion constants obtained from the vibrational data were compared with those from the data of the microwave spectra in order to confirm the reasonableness of the obtained force constants.
