ISingleElectron (cdk 2.9 API)

All Superinterfaces:

Cloneable, ICDKObject, IChemObject, IElectronContainer

All Known Implementing Classes:

DebugSingleElectron, SingleElectron, SingleElectron
```
public interface ISingleElectron
extends IElectronContainer
```
A Single Electron is an orbital which is occupied by only one electron. A radical in CDK is represented by an AtomContainer that contains an Atom and a SingleElectron type ElectronContainer:
```
   AtomContainer radical = new AtomContainer();
   Atom carbon = new Atom("C");
   carbon.setImplicitHydrogens(3);
   radical.addElectronContainer(new SingleElectron(carbon));
 
```
Source code:
main

Belongs to CDK module:
interfaces

Keywords:

radical, electron, unpaired
