The first six members of the 6<i>s</i><sup>2</sup><i>n</i><i>g</i> series of PbII were fitted to a polarization formula, from which the series limit was determined to be 121 245.14 ± 0.05 cm<sup>-1</sup>. This value is in good agreement with that determined from the same series by an extended Ritz formula, as is also the case with the <i>n</i>ƒ, <i>n</i><i>g</i>, and nh series of MgII, the <i>n</i>ƒ series of CSI, and the <i>ng</i> series of PbI. The polarization parameters empirically determined from the <i>ng</i> series of PbII were used to predict level values for the <i>nh</i> series, six members of which were subsequently found.
