The Monoclinic System is one of the seven crystal systems in crystallography. It is characterized by three unequal axes, with two axes intersecting at an angle of 90 degrees and the third axis inclined to the other two. This unique arrangement results in a variety of crystal shapes and forms, commonly found in minerals like gypsum and orthoclase. In the monoclinic system, the unit cell is defined by its dimensions and angles. The angles between the axes are crucial, with one angle being oblique while the others are right angles. This system plays a significant role in understanding the properties and behaviors of various crystalline materials.
