Moreover, you can also benefit from drawing aids for atoms, bonds, rings and molecules allowing you to work as precise as possible.

Besides the doodle board on which you do all the drawing, the application offers you a series of tools for files and formatting, strokes, labels, rings, bonds arrows, orbitals and shapes along with anything else that is required to create exactly what you need. All its toolbars and widgets can be reorganized and manipulated anyway you see fit so you can create the perfect working space. While minimizations of several discrete structures using through-space forces may look correct, please understand the theory behind the force field you are using and that any force field not specifically developed or parameterized for intermolecular forces will not lead to experimentally accurate coordinates.Whether you’re a chemistry teacher, full time chemist or just into chemistry, at one point you’ve certainly looked for a way of putting your thoughts and ideas on a digital piece of paper.ĬhemDoodle is an application designed to help you draw simple molecules, as well as create complex chemistry documents that can be used in either projects or publications.įrom the first time you run ChemDoodle and you get the feeling that this is a piece of software to which a great deal of attention has been given in terms of intuitive use, practicality, efficient workflow and an abundance of tools.ĬhemDoodle displays a user-friendly interface which can be freely manipulated. Please note, while you are able to optimize the entire scene, most force fields are not parameterized for multiple discrete molecular structures, and you will be relying on the through-space forces defined in the force field (mainly van der Waals and electrostatic), if defined at all. To do this, you can change the optimization scope to optimize the entire scene. However, you may wish to optimize several discrete molecular structures at the same time and in relation to each other.

ChemDoodle 3D therefore will optimize molecular structures separately and individually as you are editing them. Most small molecule force fields are optimized for describing individual discrete molecular structures.
