isothiocyanic acid HNCS (DNCS) and its complexes with nitrogen and xenon have been studied experimentally by FTIR matrix isolation technique and computationally with the use of ab initio calculations at the MP2 level. The spectra show that HNCS (DNCS) interacts specifically with nitrogen forming 1:1 hydrogen bonded complex in argon matrix while non-hydrogen bonded structure is probably formed in solid xenon

The complexes formed by isothiocyanicacidHNCS and its deuterated analogue DNCS with carbon monoxide have been observed and characterized in argon and nitrogen matrixes. The product bands and their shifts relative to the corresponding monomer absorptions prove that the complexes are hydrogen bonded with the carbon-attached structure OC···HNCS. The structure, energetics, and vibrational properties

A combination of matrixisolation technique and Fouriertransform infrared spectroscopy has been used to study the low-temperature photochemistry of isothiocyanic acid HNCS. Near UV photolysis with a medium-pressure mercury lamp of the matrix isolated HNCS/DNCS precursor in nitrogen and argon led to the formation of two unobserved, so far, isomers: thiocyanic acid HSCN and isothiofulminic acid HSNC
