miscellaneous topics

We finish the quadrupole interaction topic with a series of small topics which are touched in a descriptive way only.

You will get an impression

• about how to calculated electric-field gradients from first principles (the old and the new ways),
• about the effect of temperature on the quadrupole interaction,
• about energy level splitting schemes when a magnetic dipole interaction and an electric quadrupole interaction act simultaneously,
• and about the effect of a finite nucleus on the quadrupole interaction (quadrupole shift)
