Neutron spectroscopy measurements were performed on the LET (ISIS, Didcot) cold chopper spectrometer. The sample was fully protonated for these measurements, resulting in a large background from the incoherent cross section from H-atoms, as discussed below. Given the large amount of neutron incoherent scattering resulting from H and Ni, there was a significant temperature independent background in the spectroscopic data taken on LET. This primarily originated from elastic scattering leaking into inelastic channels due to instrumental effects such as finite resolution. To account for this, we have applied the principle of detailed balance to remove this background, following previous scattering studies where this has been successfully used. This analysis depends on the fact that at a fixed momentum and energy transfer, the measured intensities at the neutron energy gain (negative energy transfer) and energy loss (positive energy transfer) are related by the following expression with the energy transfer defined as 𝐸𝐸 ≡ ℏω
