Using known N3IR and structural data of solid silicates the linear correlation % = 1.187 X lo4 d(Si-0) -2014 between the isotropic z9Si NMR chemical shifts B (ppm) and the "isotropic" mean bond lengths d(Si-0) (nm) has been established. The results of semi-empirical calculations are in good agreemen
## Abstract A series of saturated __X__~__n__~H~__m__~ (__X__ being either C or Si) molecules is studied using the MINDO/3 and MNDO quantum‐chemistry procedures. We find that the proximity of H atoms tends to shorten __X____X__ bonds, and that this effect is (especially for MINDO/3) much larger th
