Atom Bond Orbital Plate GUIDE to Bond insertion

• This set is composed of various kinds of polyhedra and bonds to meet the broad demands of general research.
  
• This set is not only useful for assembling molecular models of fundamental organic compounds, but also polymer molecules, complicated steroid molecules, and some simple complex salts, etc.
  

ethylene H₂C=CH₂ (representation of -bond)

• As the bonds are made of flexible polyacetal resin, molecular models of double bonds and triple bonds, or strained ring systems such as three-and four-membered rings and particular condensed ring systms can also be properly assembled.
  
• This set contains two kinds of orbital plates, designed for patomic orbitals and for . molecular orbitals. These are useful for the explanation of the participation of -electrons, such as Woodward-Hoffman's rule.
  
• Bond distances can be easily estimated by using the unit scale (1=2.5cm) provided.
