Recent work on the H2OSO2 complex revealed several previously unmeasured ArH2S transitions. In this work, microwave transitions for ArHsS, ArHDS and ArD2S complexes are reported and a structure analysis is presented. The observation of the new set of transitions assigned to a second ArHDS isomer indicates that the hydrogens of H2S are not rapidly exchanging H for D through internal rotation. The complex is unusual in that quite large differences in the vibrationally averaged structures are seen on isotopic substitution. The apparent presence in such weakly-bound complexes of several coupled modes with large amplitude vibrations causes difficulties in obtaining a single accurate equilibrium structure.
