Stereochemistry for bonds.
|kCDCIPBondUndetermined||0||Stereochemistry has not been determined.|
|kCDCIPBondE||2||E if the highest ranking ligand of each pair is not on the same side of the bond. It is designated as E (entgegen means opposite).|
|kCDCIPBondZ||3||Z if the highest ranking ligand of each pair are on the same side of the bond, otherwise E. It is designated as Z (zusammen = together) if the groups lie on the same side of a reference plane passing through the double bond and perpendicular to the plane containing the bonds linking the groups to the double-bonded atoms.|
