Infrared spectra show both free and hydrogen bonded hydroxyl absorption in several trans-2-alkoxy-3-hydroxytetrahydrofurans. The extent of non-bonded hydroxyl is greater than that of bonded hydroxyl. Suggestions are made of possible conformations which might account for the infrared data.

The infrared spectra of the vapor and the liquid, and the Raman spectra of liquid cis and trans C2HDCl2 have been obtained in the region 400–3300 cm−1 The observed spectra are in accordance with the assignment of Bernstein and Ramsay for cis and trans C2H2Cl2 and C2D2Cl2.
