What are the types of unit cells?
Simple cubic, body-centered, and face-centered
What characterizes a simple cubic unit cell?
1 total atom; contains 1/8 of an atom at each corner
What characterizes a body-centered cell?
2 total atoms; 1 atom in the center and 1/8 of an atom at each corner
What characterizes a face-centered cell?
4 total atoms; atoms at the center of each face and 1/8 of an atom at each corner
What are the types of interferences in X-ray crystallography?
Constructive and destructive interfaces
What characterizes constructive interfaces?
A greater intensity, maxima and minima reinforce
What characterizes destructive interfaces?
A lesser intensity, maxima and minima cancel
Diffractometer
an instrument that can determine the crystal structure of a crystalline material
How does a diffractometer work?
A beam of x-ray strikes a crystalline material, producing an x-ray diffraction pattern
