Determination of Crystal Structure using powder X-Ray Diffraction
1. What is the primary purpose of using a monochromator in XRD experiments:
2. The crystal structure of Iron (Fe) at room temperature is?
3. Reflections allowed for BCC crystal are?
4. The crystal structure which has lattice parameters a = b ≠ c and angles α = β = γ?
5. In an XRD pattern, what do the peaks correspond to?
6. For a cubic crystal, a diffraction peak corresponds to h2+k2+l2=3. The Miller indices are:
7. For a fixed X-ray wavelength, a diffraction peak appears at a larger 2θ angle than another peak. What can be inferred about the corresponding interplanar spacing?
