Web1. Symmetry of the reciprocal lattice = symmetry of the unit cell. 2. Dimensions that are large in direct space are small in reciprocal space. 3. Which is a more useful parameter: q or 2 θ? Answer: q is! 4. Why? Cuz q contains info about θ and λ! 5. Peak shape has information about what? (orientation, size, strain, etc… Mehta talk). WebThe reciprocal lattice is also a lattice (and if the direct lattice is primitive, then so is the reciprocal), and points in reciprocal space are mapped out by the set of vectors: 𝑮= 1 + 2 + …

Mathematically, this can be written for any \mathbf {r} as.

Although the misleading common opinion reigns that Bragg's law measures atomic distances in real space, it does not. This first statement only seems to be true if it's further elaborated that distances measured during a Bragg experiment are inversely proportional to the distance d in the lattice diagram.
Web& Reciprocal-space notation. We introduced the use of brackets in Section 11.7. Now we’ll extend this notation to the reciprocal lattice: (hkl) is shorthand notation for a particular vector in reciprocal space because it is normal to the (hkl) plane in real space; {hkl} is then the general form for these reciprocal-lattice vectors.
