Re: Induced dipole moments




Put another way, the field of a spherical negative charge
distribution and an off-center point positive charge is not a simple
dipole.

Howdy,

Jack, I don't understand this statement. If you are OUTSIDE the
spherically symmetric negative charge distribution is MUST act like a
point charge at its center from Gauss' Law. I assume that you meant
the E-Field INSIDE the negative charge distribution is not that of a
point charge.

As a matter of fact, if the negative charge distribution is
approximately uniform and spherically symmetric the E-Field inside is
linearly increasing with distance out. Maybe that might help in
understanding why an increasing external E-Field will increase the
separation and therefore the dipole moment of the atom.

Good Luck,
