Information AboutRhombohedral |
|
In Crystallography , the rhombohedral (or '''trigonal''') Crystal System is one of the 7 lattice Point Group s. A crystal system is described by three basis Vectors . In the rhombohedral system, the Crystal is described by vectors of equal length, all three of which are not mutually Orthogonal . The rhombohedral system can be thought of as the cubic system stretched along a body diagonal. a=b=c; alpha=beta=gamma/=/90 In some classification systems, the rhombohedral system is grouped into a larger Hexagonal System . There exists only one rhombohedral Bravais Lattice . The Point Groups that fall under this crystal system are listed below, followed by their representations in international notation and Schoenflies Notation , and example Crystal s. |
