✦ Synopsis
We present the Raman spectrum of pure liquid DzO at -27.0°C, 17 °C lower than any previously reported Raman spectrum of liquid D20. The liquid's OD stretch band at -27.0°C displays a prominent feature which is clearly analogous to the u~ in-phase mode in D20 ice lh providing strong evidence that the structure of cold liquid D20's OD band is principally due to strong intermolecular coupling. Deeply supercooled liquid D20 displays this Ul in-phase feature more clearly than deeply supercooled liquid H20 due to the smaller disparity in the D/O mass ratio compared to that of H/O which enhances this coupling.
