Relationships are found between 79 measured 2J(29Si-O-29Si) couplings in oligosiloxanes and 29Si chemical shifts, number of oxygenous substituents and 1J(29Si-13C) couplings. In selected compounds the signs of the 2J couplings are positive, it is argued that all the 2J(29Si-O-29Si) couplings are positive. Density functional calculations failed to reproduce the signs and trends in the couplings.
