geometrical isomerism [¦jē·ǝ¦me·trǝ·kǝl ī`sä·mǝ´riz·ǝm] PHYSICAL CHEMISTRY The phenomenon in which isomers contain atoms attached to each other in the same order and with the same bonds but with different spatial, or geometrical, relationships; the explicit geometry imposed upon a molecule by, say, a double bond between carbon atoms makes possible the existence of these isomers. |
