The empirical correlation of 2gSi NMR chemical shifts 6 and the mean SIOT (T = Al. 5%) bond angles a in sibcates and alutiosili~tes is explained by a simple quantum-chemical model. A linear mrrelatlon 6 = 6 o + M + b cos a/(cos a -1) is derived, where n is the number of Al atoms in the Si(OSi)q \_n(

Keccivcd 16 August 19S3 '9Si MAS NMR spectra of zeolites are much sinlplified followins dealumination and the resultin\_e spectra yield a quantitxtivc correlation betnecn chemical shift and tetrahedral angle. This corrclntion is useful in the structural elucidation of zeolitts. silicas and other alu
The quantitative relationship between "52 chemical shifts 6 and SiOSi angles of framework silicates is rationalized by considering changes of the s character p of the osygen orbitals in the SiOSi D bond. A Linear correlation is established bctween 6 and p including 21 data points from 12 silica poly
## Abstract ^29^Si and ^13^C NMR chemical shifts are reported for a series of twenty 4‐substituted 2‐methoxytrimethyl‐siloxybenzenes; the set of substituents incorporates a basic set of ten substituents differing in their relative polar and resonance effects and ten other substituents which model s
