orthorhombic lattice

[¦ȯr·thə¦räm·bik ′lad·əs]
(crystallography)
A crystal lattice in which the three axes of a unit cell are mutually perpendicular, and no two have the same length. Also known as rhombic lattice.

The reduced forms 3, 11 and 38 are characteristic of a primitive cubic, primitive tetragonal, and a C-centered orthorhombic lattice, respectively.
Cell 4 defines an orthorhombic lattice whereas cell 5 of twice the volume defines a hexagonal lattice.
The reduced form type 32 is characteristic for a primitive orthorhombic lattice and reduced form 22 for a hexagonal lattice.
However, inspection of Table 3, reveals that the reduced form (reduced form number = 16) corresponds to an F-centered orthorhombic lattice. In the final study (Lattice III), Marsh and Herbstein correct the symmetry assigned to Lattice II and refine the structure in the F-centered orthorhombic lattice.
However, inspection of Table 2, reveals that the reduced form (reduced form number = 16) corresponds to an F-centered orthorhombic lattice. In the final study (Lattice V), Marsh and Herbstein correct determination 4 and refine the compound in the F-centered orthorhombic lattice.
The total number of organic compounds in all 44 reduced forms is 133 613 out of which 2978 have centered orthorhombic lattices No.
The wave-vector of the incommensurate modulation is parallel to [100] direction of the basic orthorhombic lattice. The incommensurate phase transition observed in several [Sr.sub.n][(Nb,Ti).sub.n][O.sub.3n+2] compounds were attributed to the structural distortion approximated by the alternating tilting of the (Ti,Nb)[O.sub.6] octahedra, with amplitudes varying in the direction of the modulation.
