The OH and OD uncoupled stretching vibrations of the K 4 Fe(CN) 6 · 3 H 2 O (KFCT) crystal obtained by isotope dilution technique are discussed and connected with the H bond structural characteristics. The force constants F o‐H and the anharmonicity constants 2X oH of the different OH oscillators in KFCT are calculated using the uncoupled Raman frequencies. No significant differences are found between the correlations of spectroscopic and crystallographic data in the case of weak O‐H … N and O‐H … O hydrogen bonds.
