Hydrogen Bonding in ChemBio3D

Presenter: Jesse Gordon
Company: PerkinElmer Informatics
Duration: 3 Min
Issue: 18.2

ChemBio3D automatically detects and displays hydrogen bonds both intramolecularly and intermolecularly.


ChemBio3D can detect and display hydrogen bonds in a model

Hydrogen bonds are represented as dashed lines between the donor hydrogen and the acceptor atom.

Bonds with less than ideal geometry are displayed with a blue tint. The intensity of the color increases as the bond becomes less ideal.

ChemBio3D recognizes the following:

  • Hydrogen Bond Donors:
    • *-N-H
    • *-O-H
  • Hydrogen Bond Acceptors:
    • All Oxygen atoms
    • Nitrogen atoms in delocalized systems

You can also selectively display only the polar hydrogen atoms in a model?

  • Intermolecular H-bonds to solvent
  • Intramolecular H-bonds, or both
  • Weak vs. strong H-bonds indicated
  • Polar vs. non-polar Hydrogen indicated
  • Dynamic display for trying atomic conformations
