Question

Name the parameters that characterize a unit cell.

Answer 1

The six parameters that characterise a unit cell are as follows.

(i) Its dimensions along the three edges, a, b, and c. These edges may or may not be equal.

(ii) Angles between the edges - These are the angle ∝ (between edges b and c), β (between edges a and c), and γ (between edges a and b).
