Question

What is Monoclinic?

Answer

Monoclinic crystal system is one of the 7 lattice point groups. A crystal system is described by three vectors of the cell is a parallelopiped with sides a, b and c and if α, β, γ are angle between b and c,
a, and c a and b then monoclinic is a ≠ b ≠ c and α = γ = 90° ≠ β.
