Display the Info window to view the orbital’s length and angle relative to the X-axis while you draw it. To constrain the
length and angle of an orbital, go to Object>Fixed Lengths or Fixed Angles.
Note: Orbitals are not normally part of the structure they are drawn near and are not selected when you
double-click a bond, atom, or atom label with a selection tool. To group the orbitals with the structure, go to
Object>Group. See "Grouping objects" on page 44.
S-orbitals
The s-orbital is shown below:
To draw an s orbital:
1. Hold down the mouse button over the Orbital tool and drag to select the s-orbital tool from the palette.
2. Click an atom in the drawing where the orbital will be centered.
Sigma orbitals
The sigma-orbital is shown below:
To draw a s-orbital:
1. Hold down the mouse button over the Orbital tool and drag to select the s-orbital tool from the palette.
2. Click an atom in the drawing where the orbital will be centered.
Single lobe orbitals
To draw a single lobe orbital:
1. Hold down the mouse button over the Orbital tool and drag to select the single lobe orbital tool from the palette.
2. Click an atom where the narrow end of the orbital is to be attached.
p-orbitals
The p-orbital is shown below:
To draw a p orbital:
1. Hold down the mouse button over the Orbital tool and drag to select the p-orbital tool from the palette.
2. Click an atom where the node of the orbital is to be attached.
Hybrid orbitals
The hybrid orbital is shown below:
To draw a hybrid orbital(‘sp3’):
1. Hold down the mouse button over the Orbital tool and drag to select the hybrid-orbital tool from the palette.
2. click an atom where the node of the orbital is to be attached.
