FT-IR spectra are reported for uracils complexed with hydrogen chloride in Ar matrixes. The spectral characteristics demonstrate that uracils form a C4:O···H-Cl hydrogen bond of intermediate strength in Ar matrixes. The large shift of the proton donor mode νs finds support in the vibration correlation diagram for O-base.HCl complexes. For some of the bases a small amount of the C2:O···HCl species is identified in matrixes containing an excess of HCl. H-bonding of the C:S group plays only a minor role in thiouracils. For all the bases studied here, N-H···Cl-H structures are also identified from the shifts of the uracil N-H modes. The results allow the discussion of particular bonding trends for the basic groups in uracils, these trends being largely consistent with earlier reported results for complexes of uracils with other proton donors.
