Fixed length and fixed angle drawing; Automatic alignment of figures; Detection of structures, text, and arrows, and their automatic placement; Can automatically draw rings and other structures - has all standard amino acids and nucleic acids in a built-in library; Retrieval of structures from a network database based on CAS number, formula, or ...
Expressing resonance when drawing Lewis structures may be done either by drawing each of the possible resonance forms and placing double-headed arrows between them or by using dashed lines to represent the partial bonds (although the latter is a good representation of the resonance hybrid which is not, formally speaking, a Lewis structure).
Beryllium iodide can be prepared by reacting beryllium metal with elemental iodine at temperatures of 500 °C to 700 °C: [1]. Be + I 2 → BeI 2 When the oxidation is conducted on an ether suspension of elemental Be, one obtains colorless dietherate: [5]
Draw the structure, and save it as a ChemDraw file. If you drew the structure before applying any settings, then you need to select the object, open the "Object" menu and choose "Apply document settings from → ACS Document 1996". Then save it as a PNG file, to be read by an image editor such as GIMP or IrfanView (see below for details).
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.
The Simplified Molecular Input Line Entry System (SMILES) is a specification in the form of a line notation for describing the structure of chemical species using short ASCII strings. SMILES strings can be imported by most molecule editors for conversion back into two-dimensional drawings or three-dimensional models of the molecules.
The editor can generate Daylight simplified molecular-input line-entry system (SMILES) or MDL Molfiles of the created structures. The JME Editor was written by Peter Ertl while at Comenius University in Bratislava, and then at Ciba-Geigy, later merged with Sandoz Laboratories, to form Novartis International AG, in Basel , Switzerland.
JChemPaint is computer software, a molecule editor and file viewer for chemical structures using 2D computer graphics. [1] It is free and open-source software, released under a GNU Lesser General Public License (LGPL). It is written in Java and so can run on the operating systems Windows, macOS, Linux, and Unix.
