EPR and X-ray crystallography Flashcards
1
Q
EPR
A
microwave energy absorbed by paramagnetic species (contains unpaired electrons)
2
Q
Hyperfine splitting
A
2nI+1
3
Q
X-ray Crystallography
A
regular 3D array of atoms form planes.
4
Q
Bragg’s Law
A
n(wavelength) = 2dsin(theta). In order for constructive interference to occur and a reflection to be observed, must be satisfied.
5
Q
Intensity of reflections determined by
A
position of atoms in the lattice. Type of atom.
6
Q
Space group
A
group of symmetry operations that describe how molecules are arranged in the unit cell
7
Q
Asymmetric units
A
related by symmetry, substructures within the unit cell
