To determine the most stable structure of acetic acid―SO2 complex, ab initio molecular orbital calculations were carried out. Through ab initio and DFT methods, six stable complexes were identified. The trans-acetic acid is predicted to form three stable complexes with SO2 having two pairs of interaction that S…C=O, O…HO- or S…C=O, O…HC-. The cis-acetic acid is predicted to form one stable complex with SO2 having two pairs interaction, S…C=O, O…HC-, as well as two stable complexes having only O…HO- interaction. Nonplanar trans-acetic acid complex with SO2 including S…C=O, O…HO- interaction was found to be the most stable complex.
