Experimental information on the energy distribution of states in the lowest lying configurations of selected odd-odd nuclei just beyond {sup 208}Pb is summarized. In {sup 210}Bi the {pi}0h{sub 9/2}{circle_times}{nu}1g{sub 9/2} configuration and other low lying configurations all have the inverted parabola shape in a plot of energy versus spin. When additional pairs of protons and/or neutrons are added, leading to heavier odd-odd nuclei, the inverted parabola becomes more compressed. Before these trends can be completed, however, quadrupole-octupole deformation sets in. Using the generalized intermediate coupling model, it is possible to reproduce these experimental trends and then to carry them to completion in the reversed parabola (of energy versus spin) resulting from the configuration {pi}0h{sub 9/2}{circle_times}{nu}(1g{sub 9/2}){sup {minus}1} or {pi}(0h{sub 9/2}){sup {minus}1}{circle_times}{nu}1g{sub 9/2}. {copyright} {ital 1997} {ital The American Physical Society}
