"WebJun 1, 1970 · Abstract. Infrared spectra are reported for liquid H 2 O and D 2 O using a differential technique. This technique gives sharper bands whose positions are determined with greater certainty than those reported earlier in the literature. Frequency shifts upon liquefaction give evidence for greater association in H 2 O than in D 2 O. " - Ir co2 h2o
