Monoclinic. 1/ d2 = h2 / (a2 sin 2 β) + k2 / b2 + l2 / (c2 sin 2 β) - 2 hl cos β / (ac sin 2 β) Hexagonal. 1/ d2 = 4 (h 2 + hk + k2) / 3 a2 + l2 / c2. The expressions for the general triclinic case and the trigonal with rhomobohedral axes are more complicated, and are therefore not given here.
Subroutine MAP_CRYSTAL_MET5 - University of Cambridge
MAP_CRYSTAL_MET5 calculates the metric tensor and its inverse for a monoclinic crystal structure. The first element is set to AP 2 , the fifth to BP 2 , and the ninth to CP 2 . The third and seventh elements are set to AP*CP*COS(2*pi*BETA/360) , and the rest of the elements are zero.
Subroutine MAP_CRYSTAL_TENSOR5
Calculates the metric tensor and its inverse for a monoclinic crystal. Top | Next | Prev. Specification
What is the difference between an anisotropic property and an isotropic property? Name some of each class. Which properties are likely to be tensors? What is the definition of a second rank tensor property? There are two alternative definitions, can you specify both? What are a few second rank tensor properties?
