Absence of proton tunneling during the hydrogen bond symmetrization in $\delta$-AlOOH

Florian Trybel, Thomas Meier, Biao Wang +1

$\delta$-AlOOH is of significant crystallochemical interest due to a subtle structural transition near 10 GPa from a $P{2}_{1}nm$ to a $Pnnm$ structure, the nature and origin of hydrogen di…
