Programs for Viewing Isomers and Resonance Structures of Molecules Online

Programs That Show Isomers and Resonance Structures

Yes, there are several programs and toolkits available that can generate all isomers or resonance structures for a given molecule. These tools vary in scope and accessibility, ranging from independent software to programmable libraries.

Isomer Generation: Open Molecule Generator (OMG)

The Open Molecule Generator (OMG) creates constitutional isomers from a molecular formula such as C6H6. It systematically enumerates all possible structures matching the formula.

• Generates multiple isomers based on elemental composition.
• Accessible as open-source software at SourceForge.
• Useful for exploring structural diversity and constitutional isomerism.

Resonance Structure Enumeration: Chemistry Development Kit (CDK)

The Chemistry Development Kit (CDK) is a software library that includes functions to enumerate resonance structures for molecules.

• Improves resonance structure enumeration capabilities via recent updates.
• Functions as a toolkit component, not a standalone program.
• Can be integrated into custom software or accessed via interfaces.

Using Bioclipse as an Interface for CDK

Bioclipse, an open-source workbench, interfaces with CDK and allows users to generate resonance structures without direct programming.

• Accessible for users not versed in coding.
• Provides graphical interface to input molecules and observe resonance forms.
• Alternatively, scripts can be written using CDK libraries for automated processing.

Additional Resources

The website Orgosolver Study Tools offers educational materials and may provide additional tools related to resonance and structure analysis.
