N2 - The out-of-plane (τ) H-vibration bands in spectra of polycrystalline films of two isomeric alditols, meso-erythritol and D,L-threitol, were recorded at 300 K and at 20 K for both OH and OD compounds and the H-band parameters were used for the evaluation of the relative strengths of the H- bonds in the crystals of two tetritols. Unlike erythritol, in the crystals of which all the H-bonds are strong, threitol contains additional weak H-bonds. This fact might be related to the strong water absorption capability of D,L- threitol, as compared to the reluctance of meso-erythritol to absorb water.
