Question

Unit cell parameters are determined by which of the following parameters?

(a) Double crystal X-ray photographs

(b) Single crystal X-ray photographs

(c) Double crystal Gamma rays graphs

(d) Single crystal Gamma rays graphs

The question was asked in a job interview.

Asked question is from Effect of Stress on a Powder Pattern in section X-Ray Diffraction of Solid State Chemistry

Answer 1

Right answer is (b) Single crystal X-ray photographs

The best explanation: The unit cell parameters in the crystal are often determined with the aid of single crystal X-ray photographs. The symmetry or unit cell type is first obtained from an inspection of the photographs.
