✦ Synopsis

Abstract

Silicon‐29, carbon‐13 and oxygen‐17 NMR data are reported for the methylethoxysilanes, Me~n~Si(OEt)~4−n~ with n = C to 3. The values of ^1^J(SiC) vary greatly, in a manner which appears to be inconsistent with an effect of s‐character variation alone. The chemical shifts are discussed in terms of possible π‐bonding. Silicon‐29 and carbon‐13 spin‐lattice relaxation times and nuclear Overhauser effects are also reported and discussed.

## Abstract Silicon‐29 n.m.r. was used to study the products from trimethylsilylation of minerals. Chemical shifts are reported for four model compounds, viz. the monomer, dimer, linear trimer (from natrolite) and cyclic tetramer (from laumontite). Information is then obtained from the products of
