For example, ChemDraw supports this, as does ChemSketch and BIOVIA Draw (.emf is preferable for the latter). Draw the structure in your molecule editor, and save it as a Windows Metafile (.wmf), Enhanced Metafile (.emf), or Encapsulated Postscript (.eps). Open the saved file in Inkscape.
One way to do this is to export the file to a TIFF as well as a WMF. You can then use the TIFF as a background image to get the label placement as accurate as possible. The process is basically as follows: Draw structure in ChemSketch, clean up, check stereochemistry, etc. Select structure and apply the desired style (several templates are ...
Isotopic labeling (or isotopic labelling) is a technique used to track the passage of an isotope (an atom with a detectable variation in neutron count) through chemical reaction, metabolic pathway, or a biological cell. [1] The reactant is 'labeled' by replacing one or more specific atoms with their isotopes. The reactant is then allowed to ...
Arrow pushing or electron pushing is a technique used to describe the progression of organic chemistry reaction mechanisms. [1] It was first developed by Sir Robert Robinson.In using arrow pushing, "curved arrows" or "curly arrows" are drawn on the structural formulae of reactants in a chemical equation to show the reaction mechanism.
Prior to the use of computer graphics in representing molecular structure, Robert Corey and Linus Pauling developed a system for representing atoms or groups of atoms from hard wood on a scale of 1 inch = 1 angstrom connected by a clamping device to maintain the molecular configuration. [4]
We need to discuss a variety of drawing types- simple flat drawings, 3D structures and (for the future) Jmol. This workgroup might serve as a liaison with the people writing the wiki software to ensure good compliance. We need to integrate our drawings with other chemical compound descriptions such as CAS registry number and InChI.
Microscopy is a category of characterization techniques which probe and map the surface and sub-surface structure of a material. These techniques can use photons, electrons, ions or physical cantilever probes to gather data about a sample's structure on a range of length scales. Some common examples of microscopy techniques include: Optical ...
Theories of chemical structure were first developed by August Kekulé, Archibald Scott Couper, and Aleksandr Butlerov, among others, from about 1858. [4] These theories were first to state that chemical compounds are not a random cluster of atoms and functional groups, but rather had a definite order defined by the valency of the atoms composing the molecule, giving the molecules a three ...
