Vector Notation for Dipole Moments

• We can represent polar bonds with arrows (vectors) that point in the direction of the negative pole and have a plus sign at the positive pole (as just shown for carbon dioxide).
• If the arrows (vectors) point in exactly opposing directions as in carbon dioxide, the dipole
• moments cancel.
• In the vector representation of a dipole moment, the vector points in the direction of the atom with the partial negative charge.
