Lattice dynamics and the spectroscopic signatures of H-bond disorder in $\hat{I}´$-AlOOH

Chenxing Luo, Sangjoon Lee, Hongjin Wang +2

Raman and infrared anomalies associated with H-bond symmetrization in $\hat{I}´$-AlOOH, including mode softening and linewidth broadening at 5-10 GPa, occur at significantly lower pressu…
