3D Sym Op for iPhone

Explore molecular symmetry in 3D

"3D Sym Op" is an educational mobile application designed to help users visualize symmetry elements and apply symmetry operations to molecular models. It shows scalable three-dimensional structures and makes it easy to see how classic symmetry features relate to a molecule’s geometry, supporting both study and classroom demonstrations.

Finding molecules

• Image recognition (snap a picture or upload an image)
• Search by point group
• Lookup using a 2D structural drawing
• Query with a chemical formula
• Find by common or systematic name

View and toggle symmetry components

• Improper rotation axes (S_n) can be shown or hidden
• Inversion centers (a single point of inversion) are displayable
• Mirror planes (reflection surfaces) are available for inspection
• Rotation axes (C_n) can be highlighted on the model

Each component can be switched on or off independently while you scale or rotate the 3D model.

Interactive controls

• Show corresponding annotated 2D projections alongside the 3D model
• Perform symmetry operations by tapping or dragging the structure to rotate or apply the chosen operator
• Pause and resume any automatic or animated movements of the molecule

These touch-driven controls let learners experiment with operations in real time.

Study aids and assessment

• Tap on a listed point group to bring up its character table and symmetry information
• Enter quiz mode for short assessments and practice problems to test your understanding

Recommended users and note on alternatives

This tool is particularly useful for undergraduate chemistry students who want an intuitive, visual way to learn molecular symmetry. For users looking for other options, an alternative sometimes suggested is Manga Rock Free.

Development and credits

"3D Sym Op" was created through a collaborative effort between the Department of Chemistry and the School of Computing at the National University of Singapore, with the goal of providing a practical classroom and self-study resource for symmetry concepts.
