Class: BondStereo

Kekule. BondStereo

new BondStereo()

Enumeration of possible stereo types of two-atom bonds. The Stereo type defines not just define the stereochemistry, but also the which atom is the stereo center for which the Stereo is defined. The first atom in the bond (index = 0) is the start atom, while the second atom (index = 1) is the end atom.

Members

(static) CIS

Indication that this double bond has a Cis configuration.
Source:

(static) CIS_OR_TRANS

Indication that this double bond has a fixed, but unknown cis/trans configuration.
Source:

(static) CLOSER

A bond is closer to observer than papaer, often used in ring structures.
Source:

(static) DOWN

A bond pointing down of which the start atom is the stereocenter and the end atom is below the drawing plane.
Source:

(static) DOWN_INVERTED

A bond pointing down of which the end atom is the stereocenter and the start atom is below the drawing plane.
Source:

(static) E

Indication that this double bond has a E configuration.
Source:

(static) E_OR_Z

Indication that this double bond has a fixed, but unknown E/Z configuration.
Source:

(static) E_Z_BY_COORDINATES

Indication that this double bond has a fixed configuration, defined by the 2D and/or 3D coordinates.
Source:

(static) NONE

A bond for which there is no stereochemistry.
Source:

(static) TRANS

Indication that this double bond has a Trans configuration.
Source:

(static) UP

A bond pointing up of which the start atom is the stereocenter and the end atom is above the drawing plane.
Source:

(static) UP_INVERTED

A bond pointing up of which the end atom is the stereocenter and the start atom is above the drawing plane.
Source:

(static) UP_OR_DOWN

A bond for which there is stereochemistry, we just do not know if it is UP or DOWN. The start atom is the stereocenter.
Source:

(static) UP_OR_DOWN_INVERTED

A bond for which there is stereochemistry, we just do not know if it is UP or DOWN. The end atom is the stereocenter.
Source:

(static) Z

Indication that this double bond has a Z configuration.
