The absolute values of spin–spin couplings between 29 Si nuclei in siloxanes, 2 J ( 29 SiO 29 Si), were determined. The couplings are small and cover a narrow range of values (0–5 Hz). The coupling constants depend on the branching or on the number of electronegative substituents on the SiOSi moiety. Copyright © 2007 John Wiley & Sons, Ltd.
