Monoclinic system
On the basis of crystallographic axes the crystals can be grouped into different
crystal systems. On the basis of symmetry crystals can be classified into
symmetry classes. There are thirty-two classes of symmetry.
Cubic system - Crystals of this system has three axis
of equal lengths, which are at right angle to each other and are denoted by
a1,a2 and a3.
Tetragonal system - The crystals of this system
have two equal horizontal axis and one vertical axis, at rigth angle to each
other denoted by a1,a2 and c.
Hexagonal system -
Orthorhombic system -
Monoclinic system -
Triclinic system -
