ChemDoodle 9.1.0

The graphic representation of the structure of a chemical substance allows us to read easily the relevant information about the substance, as well as the way it interacts with other substances or elements.

ChemDoodle is a program that lets you draw these graphic representations in a relatively easy manner. It has many drawing tools, but unlike other conventional drawing programs, these tools are used in very specific forms. For example, the cursor acts as if it was an electron from which you can draw other chemical compounds. You can change the attributes of the cursor to draw two electrons, radicals, a pair of electrons in a bar format, and so on. You can also add different types of rings and paste different tags such as the abbreviations of the chemical elements from the periodic table (for example, Au for gold), as well as custom texts.

The program is not very easy to use and learn. First, you need good knowledge of chemistry to use it at its full potential. Also, you need to know all the symbols and conventions used in chemistry to draw accurate graphics. Also, its price tag is rather high. There is a limited, more affordable student version, as well as an advanced 3D one. You can choose the version that best suits your needs.

You can use the free shareware version for 14 days. If you like the program and want to use it longer, then you will need to purchase a license.
