ChemDoodle 3D can now generate the Framework Group and Vibrational Representation descriptors for built molecules.

Executive Summary

ChemDoodle 3D v7.3 adds even more symmetry features, support for atropisomer stereochemistry and additional tools for selecting and duplicating content, among other improvements.

Additions

  1. Added Framework Group and Vibrational Representation descriptors to the Symmetry widget. These new symmetry features were developed in collaboration with Professor Dean Johnston and symotter.org.
  2. A new Symmetry widget option allows you to select how the center of mass is defined.
  3. Information from the Symmetry widget can now be easily copied to the system clipboard using a button.
  4. Stereochemistry support for atropisomers is implemented.
  5. Double clicking on an atom or bond using a selection tool will now select the entire molecule by default. You may set this back to editing styles in the Settings window under the Controls tab.
  6. Pressing the command key on macOS or the Ctrl on Windows/Linux will now duplicate your structure while you are starting or performing a transform action.

Fixes

  1. "Every" symmetry components will now be properly loaded from IC3 files.
  2. Pressing the comma key while an electron is hovered now properly shows the electron styles window.
  3. Prevented keyboard tool shortcut from executing when completing some menu accelerator commands.
