The infrared and Raman spectra of crystalline deltic acid and its deuterated derivative have been investigated in the 4000–20[Formula: see text]cm−1 range. An assignment of all the intramolecular fundamentals has been proposed assuming a C2v molecular symmetry. The crystal symmetry is likely to be described by the [Formula: see text] or P2/m space group with Z = 2. Deltic acid molecules probably form infinite chains linked with two very strong, asymmetric, and different OH … O hydrogen bonds, with O … O distances estimated at 2.49 and 2.56 Å.
