(I'm also unclear how the bit is supposed to actually flip under the applied electric charge without the fluorine and carbon having to pass through each other.)

Technical note, because it's jargon:
"Real" means position = A * sin(w * t)
"Imaginary" means position = A * expt(w * t)
(because expt(w * i * t) = cos(w * t) + i * sin(w * t))
If you calculate in a computer an ammonia molecule with all the atom is a plane z = 0 (instead of the usual piramidal shape), then the N in the center is in an inestable equilibrium and the N does not make small vibrations like z = expt(w * t).
It makes a big "imaginary" vibration like z = expt(w * t) that is exponential for a short time while z is almost 0, and then the approximations don't apply and it reach the z of the usual shape at equilibrium.
