25. In addition to its permanent dipole component, the NC may carry an additional contribution that results from the polarization of the NC by the strong fields caused by its neighbors. Depending on the exact charge distribution, we estimate the induced dipole to be 30 to 50 D for the 6.8 nm PbSe NCs. This value is an order of magnitude lower than the total dipole moment, which is, thus, dominated by the permanent component.
