摘要：

The 2D silicon-29-silicon-29 INADEQUATE experiment provides connectivity information in systems whose skeleton is composed entirely of Si-Si bonds. We have developed this method to confirm the structure of the first generation dendritic polysilane [(Me3Si)(2)SiMeSiMe2](3)SiMe. The 2D spectrum demonstrates connectivity for each of the three Si-Si bonds in the molecule. This method should be generally useful for dendritic and branched polysilanes.
