In
crystallography, the
orthorhombic crystal system is one of the seven lattice
point groups. Orthorhombic
lattices result from stretching a
cubic lattice along two of its orthogonal pairs by two different factors, resulting in a rectangular
prism with a rectangular
base (
a by
b) and height (
c), such that
a,
b, and
c are distinct. All three bases intersect at 90° angles. The three lattice vectors remain mutually
orthogonal.
