Polarised spectra measured parallel to principal crystallographic axes for [triv] experiments (Sc-doped), ordered from highest water activity (top) to lowest (bottom). Spectra are the average of multiple measurements, normalised to 1 cm and offset for clarity. The indicated band positions are (1) 3355 cm−1, (2) 3355 cm−1, (3) 3320 cm−1, (4) 3355 cm−1, (5) 3320 cm−1 and (6) 3160 cm−1
