Phase | a | b | \(\sigma _{aa}\) | \(\sigma _{ab}\) | \(\sigma _{bb}\) |
|---|---|---|---|---|---|
Water | 1.020 ± 0.001 | 0.314 ± 0.001 | \(1.632 \times 10^{-6}\) | \(-1.381\times 10^{-6}\) | \(1.175 \times 10^{-6}\) |
Ice VI | 1.064 ± 0.010 | 0.285 ± 0.007 | \(9.451 \times 10^{-5}\) | \(-6.751 \times 10^{-5}\) | \(4.824 \times 10^{-5}\) |
