Such spatial arrangements require that the ENDOR spectra are recorded at different magnetic field settings within the EPR powder pattern.
2.
Every crystalline solid will have a unique pattern of d-spacings ( known as the powder pattern ), which is a finger print for that solid.
3.
They also assumed that the mineral was identical to the species occurring in the Ag-As-Sb vein deposit at Alacran due to the similarity of its X-ray diffraction powder pattern.
4.
Whereas, previously, powder burns had been detectable only in cases where the person had been shot at close range, his test would reveal the " entire powder pattern from shots fired at a much greater distance & by locating each individual grain of powder in the exact position in which it lies upon the cloth ."
