... a polar vector, the diagonal elements of the perturbation matrix Vint vanish for systems with an inversion center (such as atoms) ... Molecules with an inversion center in a non-degenerate electronic state do not have a (permanent) dipole and hence do not show a linear Stark effect ... In order to obtain a non-zero matrix Vint for systems with an inversion center it is necessary that some of the unperturbed functions have opposite parity (obtain plus and minus under ...

Famous quotes containing the word center:

    Whenever there’s a big war coming on, you should rope off a big field. And on the big day, you should take all the kings and their cabinets and their generals, put ‘em in the center dressed in their underpants and let them fight it out with clubs. The best country wins.
    Maxwell Anderson (1888–1959)
