WebResolution in terms of electron density is a measure of the resolvability in the electron density map of a molecule. In X-ray crystallography, resolution is the highest resolvable peak in the diffraction pattern, while resolution in cryo-electron microscopy is a frequency space comparison of two halves of the data, which strives to correlate with the X-ray definition. WebCrystal Systems The 32 point groups are collected into 7 crystal systems: triclinic, monoclinic, orthorhombic, tetragonal, trigonal, hexagonal, and cubic, based upon the presence of shared point group symmetry operations and listed in Table 1.

WebNov 17, 2024 · Structures determined by X-ray crystallography are typically deposited as files containing the coordinates for one asymmetric unit (ASU). Knowledge of the symmetry operators that describe how the ASUs are arranged relative to each other allows the arrangement of the crystal lattice to be recreated. WebWe will deal with the symmetries in more detail in the lecture on crystal phyiscs. I will introduce the concept of the asymmetric unit which is not in these books but is an important concept for crystallography.
