absorption (polarized 3 He). In the latter case, 3 He has to be polarised first and then placed in cells called "spin filters", hence Tyrex-2 . This approach provides very interesting properties: simple

inhibitors, and the orientation of water molecules. Data collection is feasible for samples with unit-cell edges ranging from 50 to ~150 Å using crystal volumes from ~0.05 to 0.5mm 3 , respectively .
