An analysis of Gamow-Teller β-decay data is used to derive information on the structure of J = 1 levels in sd-shell T = 0 odd-odd nuclei within the context of an extended Interacting Boson Model (IBM-4), in particular on the relation of their orbital wavefunctions to those of levels in the neighboring T = 1 systems. The data systematically indicate that the orbital wavefunctions of the even-even ground states are generally those of levels at high excitation in the odd-odd nuclei. Predictions are made for which even-even states do have similar orbital structure to the odd-odd ground states.
