A quantum mechanical study of the potential energy surface for the HNCS dimer is reported. The calculations were performed using DFT and ab initio MP2 methods. The most stable is a cyclic form with a double N–H⋯S interaction and the interaction energy in the range of 16.91–18.92 kJ mol−1. An open HNCS dimer bound by the N–H⋯N hydrogen bond is by ca 3.3–5.1 kJ mol−1 less stable. Experimental FTIR matrix isolation studies of HNCS/N2 system show that exclusively less stable open dimer is formed in solid nitrogen. Possible reasons for the observed discrepancy between theory and experiment are discussed.
