The complexes formed by dimethylsulphide (DMS) and dimethyldisulphide (DMDS) with two isomers of nitrous acid have been observed, and characterised in argon and nitrogen matrices. The v(1) OH stretching vibration of the perturbed trans-HONO monomer is 425 and 294 cm(-1) red shifted, respectively, for the DMS and DMDS complex in solid argon, and 441 and 301 cm(-1) in solid nitrogen. A large blue shift is also observed for the v(3) NOH in-plane deformation mode: 101 and 80 cm(-1) for DMS-HONO-trans in argon and nitrogen matrices and 46 cm(-1) for DMDS-HONO-trans in nitrogen matrix. The results indicate formation of strong hydrogen bonds in the studied DMS-HONO and DMDS-HONO systems. The origin of the complicated shape of the v(1) OH absorption is discussed. Similarities and differences between argon and nitrogen matrices are considered. (C) 2000 Elsevier Science B.V. All rights reserved.
