  2. Chemical file format - Wikipedia

    en.wikipedia.org/wiki/Chemical_file_format

    A chemical file format is a type of data file which is used specifically for depicting molecular data. One of the most widely used is the chemical table file format, which is similar to Structure Data Format files. They are text files that represent multiple chemical structure records and associated data fields.

  3. XYZ file format - Wikipedia

    en.wikipedia.org/wiki/XYZ_file_format

    The XYZ file format is a chemical file format. There is no formal standard and several variations exist, but a typical XYZ format specifies the molecule geometry by giving the number of atoms with Cartesian coordinates that will be read on the first line, a comment on the second, and the lines of atomic coordinates in the following lines.

    SDF is one of a family of chemical-data file formats developed by MDL; it is intended especially for structural information. "SDF" stands for structure-data format, and SDF files actually wrap the molfile (MDL Molfile) format. Multiple records are delimited by lines consisting of four dollar signs ($$$$). A key feature of this format is its ...

    Draw the structure in your molecule editor (ideally change the settings to give a molecule twice the size as the JACS standard or change the size to 200% before next step), and save it as an Encapsulated PostScript file (.eps) - many of the Apple print drivers (an Apple printer is not required) that print to a PostScript printer can be set to ...
