Chlorine trifluoride has three polarized bonds and they combine to produce a small molecular dipole along the Cl-F bond. Bromotrichloromethane is tetrahedral. The less polar C-Br bond does not quite balance the more polar C-Cl bonds so there is a small molecular dipole.
The bond dipole moment uses the idea of the electric dipole moment to measure a chemical bond's polarity within a molecule. This occurs whenever there is a separation of positive and negative charges due to the unequal attraction that the two atoms have for the bonded electrons.
