WebJun 9, 2014 · A comparison of bond lengths and bond angles between pure ice and Ne hydrate is shown in Table 2. Insertion of Ne atoms into the ice structure leads to increases of the deuterium bond distances D1–O1, D3–O2, and D4–O1. This, in turn, results in the lengthening of O1–O1 and O2–O2 distances.
