Morino, Yonezo published the artcileDipole moments of 2,3-dihalo-2,3-dimethylbutane, Recommanded Product: 2,3-Dibromo-2,3-dimethylbutane, the publication is Bulletin of the Chemical Society of Japan (1955), 165-71, database is CAplus.
cf. C.A. 45, 947i; 48, 13297h. The dipole moments of X(Me)2CC(Me)2X [where X = Cl(I) and Br(II)] are 1.24, -; -, 0.88; 1.30, -; -, 0.97; 1.37, 1.03; and 1.47, 1.15 for -20; -15; 0; 6; 25; and 55°, resp., in CCl4, and 1.74, 1.24 D. at 25° in C6H6. These data indicate the existence of a rotational isomer or gauche form with a ΔΕ of 1.1 and 1.3 for I and 1.5 and 1.5 kcal./mole for II in CCl4 and heptane, resp. The dipole moments of the gauche form are 2.8 and 3.2 for I and 2.6 and 2.6 D. for II in CCl4 and heptane, resp.
