An analysis of the Raman and infrared spectra of di‐potassium tartrate hemi‐hydrate (DKT), K 2 C 4 H 4 O 6 ·½H 2 O, is reported. It has been inferred that the C 4 H 4 O 6 2−ion and H 2 O molecule in a DKT crystal occupy points of C 1 site symmetry. Various units of C 4 H 4 O 6 2−ion/(H 2 O molecule) located at crystallographically distinguishable positions in this crystal do not appear to be different in their structure or the force fields governing their vibrational dynamics.
