The Builder Palette
The Builder palette includes the
buttons for viewing and modifying the structural parameters of
molecules. It is illustrated below:

The Builder Palette
The buttons have the following uses:
- Element Fragment: Open the Element Fragments palette.
- Ring Fragment: Access a palette of ring
structures.
- R-Group Fragment: Summon a palette of
functional group fragments.
- Biological Fragment: Summon a palette of
amino acid and nucleoside fragments.
- Custom Fragment: Access a custom
fragment library.
- New Molecule Group: Create
a new molecule (per submenu
selection).
- Rebond: Initiates a
rebonding process
in which GaussView reidentifies bonded atoms, based on a distance
algorithm. Note that Gaussian usually does not use the bond information
on the screen for calculations. This information is presented primarily
to make it convenient for you to visualize the chemistry of the
molecule.
- Current Fragment: Submenu displays a
list of
fragments of the checked type.
- Place Fragment at Centroid of Selected Atoms:
Places an atom at the centroid position of the currently selected atoms.
- Modify Bond: Access the Bond SmartSlide dialog after two atoms are
selected.
- Modify Angle: Access Angle SmartSlide dialog after three atoms are
selected.
- Modify Dihedral: Access Dihedral SmartSlide
dialog after four atoms are selected.
- Inquire: Examine structural data for the
current molecule.
- Add Valence: Add an additional hydrogen
to the selected atom.
- Delete Atom: Eliminate atoms and/or open
valences (dangling half bonds).
- Invert Atom: Invert molecular structure
about a selected atom.
- Select Atoms by Clicking: Select atoms
by clicking on them.
- Select Atoms by Rubberband: Select atoms
by clicking and dragging a marquee enclosing them.
- Select Atoms by Brush: Select atoms by
clicking and dragging a marquee enclosing them.
- Deselect All Atoms: Deselect all
currently selected atoms.
- Select All Atoms: Select all atoms.
- Symmetrize: Apply
point group symmetry to
the current model.
- Clean: Adjust
molecular geometry
according to a set of rules designed to match chemical intuition.
- Builder Help: Open
the GaussView help facility.
