Experimentally observed energy levels for odd-odd nuclei with 87 {le} Z {le} 103 and 120 {le} N {le} 159 are classified in terms of their intrinsic structures and associated rotational bands. Distinctive level patterns for different nuclear shapes are discussed. Parity-mixed level structures indicative of reflection-asymmetric (octupole-deformed) shapes are seen in N < 139 nuclides. For well-deformed nuclei, long-lived (t{sub 1/2} {ge} 1 s) isomer pairs are observed in several cases with no isomeric transition connecting the two isomers. Systematics of residual interaction effects, e.g., Gallagher-Moszkowski splittings and Newby shifts, are studied and features of interaction matrix elements are examined. The literature cutoff date is September 1993. 47 refs., 5 figs., 3 tabs.
