The infrared spectra and the Raman spectrum of N,N-dimethylthioacetamide are recorded. Normal coordinate treatment of N,N-dimethylthioacetamide is carried out and the force constants are refined by the damped least squares technique. The potential energy distributions in both general quadratic space and symmetry coordinates are computed. Vibrational assignments of all the inplane vibrations and some of the out-of-plane vibrations are made. The nature of the absorption bands is discussed in relation to the mixing of the skeletal modes of vibration. The vibrational mean amplitudes are also calculated.
