Adiabatic {ital R}-matrix scattering calculations for vibrationally resolved resonance series {ital a, b}, and {ital c} are presented and compared with experimental studies for e-H{sub 2}, e-D{sub 2}, and {ital e}-HD. The excellent agreement allows a complete theoretical explanation of the series from which definitive assignments of parentage and symmetry can be made. It also explains the long-standing disagreements among and between previous theoretical and experimental results. More generally, these results provide the first corroboration of the idea of multiple parent states and parent state swapping of Feshbach-type resonances in molecules. {copyright} {ital 1997} {ital The American Physical Society}
