8,789 structures were reported in New Journal of Chemistry. These 25 journals account for 704,541 of the 996,193 or 70.7% of the structures in the CSD. These data show that most structures are determined by X-ray diffraction, with less than 1% of structures being determined by neutron diffraction or powder diffraction. The number of error-free ...
Both Jmol and JSmol render an interactive 3D representation of a molecule or other structure that may be used as a teaching tool, [5] or for research, in several fields, e.g. chemistry, biochemistry, materials science, crystallography, [6] symmetry or nanotechnology.
A notable molecule editor is a computer program for creating and modifying representations of chemical structures.. Molecule editors can manipulate chemical structure representations in either a simulated two-dimensional space or three-dimensional space, via 2D computer graphics or 3D computer graphics, respectively.

3D structure A Newman projection is a drawing that helps visualize the 3-dimensional structure of a molecule. [ 1 ] This projection most commonly sights down a carbon-carbon bond, making it a very useful way to visualize the stereochemistry of alkanes.
Structural chemistry is a part of chemistry and deals with spatial structures of molecules (in the gaseous, liquid or solid state) and solids (with extended structures that cannot be subdivided into molecules). For structure elucidation [1] a range of different methods is used.
Ribbon diagrams, also known as Richardson diagrams, are 3D schematic representations of protein structure and are one of the most common methods of protein depiction used today. The ribbon depicts the general course and organization of the protein backbone in 3D and serves as a visual framework for hanging details of the entire atomic structure ...
