A comparative study of infrared absorption due to H 2 O and D 2 O impurities in a fluorozirconate glass (53ZrF 4 ·20BaF 2 ·4LaF 3 ·3AlF 3 ·20NaF) was carried out. The H 2 O and D 2 O were introduced into the glass by reaction of the surface at 260°C with H 2 O and D 2 O vapor entrained in a stream of N 2 . Reaction with H 2 O produced IR absorption bands at 2.9 μm (O–H stretch) and 6.1 μm (H 2 O bend). Reaction with D 2 O produced bands at 3.9 μm (O–D stretch) and 8.3 μm (D 2 O bend). The ratios of the corresponding D 2 O/H 2 O peak frequencies are 0.74 for both the stretching and bending vibrations, in good agreement with the value of 0.727 predicted from the difference in the OH and OD reduced masses.
