Vibrational spectrum of the proton network in the double hydroxide perovskite CuSn(OH)6
This is a test measurement to test the feasibility of measuring the proton vibrational spectrum on Lagrange. We will use Lagrange to obtain the vibrational spectrum of the H..O-H bond network in the double hydroxide perovskite CuSn(OH)6. We succeeded in refining the structure of this compound including hydrogen positions for the first time. The material features correlated proton disorder governed by its own "ice rules", similar to that in water ice. The goal of the present experiment is to get an independent confirmation of the structure by extracting the OH bond lengths and hydrogen bond angles from the vibrational spectrum. We see this an an essential intermediate step in understanding the proton network, its disorder, dynamics, and ultimately the interplay with magnetism in a proton-disordered S=1/2 magnetic material. If our approach proves successful, other transition-metal hydroxide perovskites will be investigated in follow-up experiments.
