orthorhombicadj.

Brit.

/ˌɔːθəˈrɒmbɪk/, U.S.

/ˌɔrθoʊˈrɑmbɪk/

Origin: Formed within English, by compounding; modelled on a German lexical item. Etymons: ortho- comb. form, rhombic adj.

Etymology: < ortho- comb. form + rhombic adj., after German orthorhombisch (J. F. L. Hausmann Handb. der Mineral. (ed. 2) (1847) II. i. p. xiii). Compare French orthorhombique, orthorrhombique (1851).

Crystallography.

Designating or relating to a crystal system referred to three unequal axes which intersect each other at right angles.

1854 J. D. Dana Syst. Mineral. (ed. 4) I. i. i. 29 The name Trimetric alludes to the existence of axes of three kinds, (the three being unequal). [Note] Trimetric and Orthorhombic of Hausmann.

1878 H. P. Gurney Crystallogr. 37 There may be three planes of symmetry at right angles. Such crystals belong to the Orthorhombic System.

1920 Proc. National Acad. Sci. U.S.A. 6 450 Mineralogically, the chondrules..in nearly all meteorites are composed chiefly of the minerals olivine or pyroxene, the latter in either orthorhombic or monoclinic forms, or both.

1940 Amer. Mineralogist 25 513 A few specimens contain orthorhombic crystals distinct from any previously described mineral.

1984 N. N. Greenwood & A. Earnshaw Chem. of Elements (1986) v. 119 The deposits are of two main types—rhombohedral calcite, which is the more common, and orthorhombic aragonite.

2002 Jrnl. Pharmacy & Pharmacol. 54 325 Orthorhombic paracetamol exhibits far better tabletability than the monoclinic form.
