Abstract
Solid-state Si-29 NMR has been used to determine the principal values of the shielding tensors for organosilicon compounds, including cyclic silanes. Silicon atoms in three-membered rings show exceptionally lar ge chemical shift anisotropies, similar to those of multiply-bonded Si atoms. Possible reasons for these large CSA's are discussed.
